[PSM Interop] Simplify PSM Interop Kokoro buildscripts (v1.58.x backport) (#36539)

Backport of #36450 to v1.58.x.
---
Integrates the new features of the the Kokoro PSM Interop install
library introduced in grpc/psm-interop#73.

Nearly all common functionality was moved from per-language/per-branch
PSM Interop build scripts to
[psm_interop_kokoro_lib.sh](https://github.com/grpc/psm-interop/blob/main/.kokoro/psm_interop_kokoro_lib.sh):
1. The list of tests in the each test suite 
2. Per-test-suite flag customization
3. `run_test` methods
4. `build_docker_images_if_needed` methods
5. Generic `build_test_app_docker_images` methods (simple docker build +
docker push + docker tag). grpc-java is one exception, as it doesn't run
docker directly, but a cloudbuild flow.

Now all PSM Interop jobs share the same buildscripts by all test suites:
1. buildscript that invokes the test: `psm-interop-test-{language}.sh`
(configured as `build_file` in the build cfg)
2. buildscript that builds the xDS test client/server and publishes them
as a Docker image: `psm-interop-build-{language}.sh` (conventional name
called from `psm_interop_kokoro_lib.sh`)

`psm-interop-test-{language}.sh`:
1. Sets `GRPC_LANGUAGE`, `BUILD_SCRIPT_DIR` environment variables.
2. Downloads the shared `psm_interop_kokoro_lib.sh` from the main branch
of the psm-interop repo.
3. Sources `psm-interop-build-{language}.sh`
4. Calls `psm::run "${PSM_TEST_SUITE}"` (`PSM_TEST_SUITE` configured in
the cfg file).

`psm-interop-build-{language}.sh`:
1. Defines `psm::lang::build_docker_images` which is called from
`psm_interop_kokoro_lib.sh`.
2. Invokes any repo-specific logic.
3. May use `psm::build::docker_images_generic` for generic Docker build,
tag, push, or provide implement its own build/publish method.

-NOTE: If you're using Bazel 7 or newer and working with gRPC, you'll need to turn off bzlmod.
-This is because gRPC isn't fully compatible with bzlmod yet. To do this, add --enable_bzlmod=false to your Bazel commands.
-
 NOTE: If you are a gRPC maintainer and you have access to our test cluster, you should use our [gRPC's Remote Execution environment](tools/remote_build/README.md)
 to get significant improvement to the build and test speed (and a bunch of other very useful features).

-# Contributing to gRPC: A Step-By-Step Guide
-
-Note: This document is not meant for Google employees.
-
-## Prerequisites
-
-To contribute to the gRPC codebase, you need the following:
-
-1.  An
-    [active GitHub account](https://docs.github.com/en/get-started/quickstart/creating-an-account-on-github)
-1.  [An understanding of Git and GitHub](https://docs.github.com/en/get-started/using-git/about-git)
-1.  [Knowledge of how to fork a repository, clone a repository, merge, rebase,
-    resolve, push, pull, fetch
-    etc.](https://docs.github.com/en/get-started/using-git/about-git)
-1.  [git installed and working on your machine](https://github.com/git-guides/install-git)
-1.  Knowledge of the language being used, which can be C++, Python, Ruby,
-    Objective-C, PHP, or C#.
-
-## Steps to Contribute gRPC C++ Code
-
-The GitHub repository for the C-based gRPC (C++, Python, Ruby, Objective-C, PHP, C#)
-is at https://github.com/grpc/grpc.
-
-### Fork and Clone the Repository
-
-If you want to contribute to the gRPC code base, you need to make a fork of the
-repository.
-
-1.    Create your
-[own fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo)
-from https://github.com/grpc/grpc.
-
-      ![Screenshot of creating fork using a non-google account.](doc/images/img/grpc-create-fork.png)
-
-1.   [Clone your fork](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/fork-a-repo#cloning-your-forked-repository)
-on your local machine.
-
-### Prepare and Push Your Commit
-
-1.  In your cloned repository, create a new branch from `master`.
-1.  Then prepare a commit for the files that you want to contribute.
-1.  Commit to this branch.
-1.  Push the commit to your fork on GitHub.
-
-Take care that your commits are aligned with these
-[guidelines](https://github.com/grpc/grpc/blob/master/CONTRIBUTING.md#guidelines-for-pull-requests).
-
-### Prepare a Pull Request
-
-After pushing your commit, visit https://github.com/grpc/grpc . If the
-forking, branch creation, commit and push have been successful, you will see
-the following message:
-
-![Screenshot of Github UI to help to create a pull request.](doc/images/img/grpc-compare-and-pull-request.png)
-
-Take care to allow edits by maintainers. If there is a specific issue
-with your pull request, the maintainer can help if needed. This access to help will reduce
-the turnaround time for your submission.
-
-![Screenshot of Github UI to help to create a Pull Request.](doc/images/img/grpc-pull-request-details.png)
-
-Create a pull request.
-
-### Pull Request Status - Safe Review
-
-Once the pull request is ready, you must wait for a reviewer to be
-assigned to your pull request.
-
-If you see *Not Covered* in the EasyCLA screen, as shown in the following image,
-click on the mentioned link to start the authorization process.
-
-![Screenshot of waiting for safe review](doc/images/img/grpc-tests.png)
-
-You will see a series of screens:
-
-1.  Select *Authorize LF-Engineering:
-
-![Screenshot of EasyCLA Step 1](doc/images/img/grpc-easycla-authorize.png)
-
-1.  Select your contributor type:
-
-![Screenshot of EasyCLA Step 2](doc/images/img/grpc-contributor-type.png)
-
-1.  Select *SIGN CLA*:
-
-![Screenshot of EasyCLA Step 3](doc/images/img/grpc-sign-cla.png)
-
-Some time after you've digitally signed the document, the EasyCLA will appear as
-*Covered*.
-
-![Screenshot of EasyCLA Step 5](doc/images/img/grpc-easycla-covered.png)
-
-    After a few hours, you will notice a new "assignee" assigned to the pull request. 
-
-![Screenshot after an assignee is added](doc/images/img/grpc-assignee.png)
-
-After a reviewer is assigned to you, they will help with the next
-steps, which are as follows:
-
-1.  You complete the code review and address the comments.
-1.  Your reviewer may add a few labels as needed.
-
-### Pull Request Status - Green
-
-Once you have approval from the reviewer, check if the tests are running. After
-the tests are complete, look at the status of all the tests. If
-everything is green, everything is good. But usually some failures exist. If
-there are failures, select each failure. The selection will take you to a page
-that has error details. Try to fix the issue.
-
-### Pull Request Approval
-
-For pull requests that are non-trivial, there is a thorough code review process.
-You can read more about the process and requirements
-[here](https://github.com/grpc/grpc/blob/master/CONTRIBUTING.md#guidelines-for-pull-requests).
-
-After you fix the code review, you will finally get an approval. After getting
-approval, you can submit the pull request.
-
-![Pull request approved and labelled](doc/images/img/grpc-review-complete.png)
-
-### Submission
-
-You **cannot** do submission or merge of a pull request through Github.
-
-![Pull request approved and labelled](doc/images/img/grpc-wait-for-merge.png)
-
-After you have approval from a reviewer, a Google employee will trigger
-the submission process. When the submission happens:
-
-1.  A commit with your changes, along with a few additional formatting changes, will
-    be committed to the `grpc/master` branch.
-![Copybara commit](doc/images/img/grpc-copybara-commit.png)
-
-1.  The pull request you originally created will be closed.

 `GRPC_TRACE` can be used to enable extra logging for some internal gRPC components. Enabling the right traces can be invaluable
 for diagnosing for what is going wrong when things aren't working as intended. Possible values for `GRPC_TRACE` are listed in [Environment Variables Overview](doc/environment_variables.md).
 Multiple traces can be enabled at once (use comma as separator).

 ## Core functionality
 
 The command line tool can do the following things:
 
--   Send unary rpc.
--   Attach metadata and display received metadata.
--   Handle common authentication to server.
--   Infer request/response types from server reflection result.
--   Find the request/response types from a given proto file.
--   Read proto request in text form.
--   Read request in wire form (for protobuf messages, this means serialized
-    binary form).
--   Display proto response in text form.
--   Write response in wire form to a file.

-# Authentication Example
-
-## Overview
-
-SSL is a commonly used cryptographic protocol to provide end-to-end
-communication security. In the example, we show how to set up a server
-authenticated SSL connection to transmit RPC.
-
-We provide `grpc::SslServerCredentials` and `grpc::SslCredentials` types
-to use SSL conections.
-
-In our example, we use the public/private keys created ahead: 
-* "localhost.crt" contains the server certificate (public key). 
-* "localhost.key" contains the server private key. 
-* "root.crt" contains the certificate (certificate authority)
-that can verify the server's certificate.
-
-### Try it!
-
-Once you have working gRPC, you can build this example using either bazel or cmake.
-Make sure to run those at this directory so that they can read credential files properly.
-
-Run the server, which will listen on port 50051:
-
-```sh
-$ ./ssl_server
-```
-
-Run the client (in a different terminal):
-
-```sh
-$ ./ssl_client
-```
-
-If things go smoothly, you will see the client output:
-
-```
-Greeter received: Hello world
-```
