Closes#36887
COPYBARA_INTEGRATE_REVIEW=https://github.com/grpc/grpc/pull/36887 from XuanWang-Amos:bump_core_version_202406111526 5df15650dd
PiperOrigin-RevId: 642358496
All TraceFlags are now configured in `src/core/lib/debug/trace_flags.yaml`. The format is:
```
my_flag:
default: false # the default value; default=false
description: Some Description
debug_only: false # debug_only flags only work in debug builds; default=false
internal: false # internal flags will not show up in documentation; default=false
```
To regenerate the trace flag source code, run `tools/codegen/core/gen_trace_flags.py` (requires mako). This script is also run when sanity checking.
This PR also adds two new features:
### Glob-based flag configuration
Trace flag configuration now supports `?` (single wildcard character) and `*` (one or more wildcard characters). For example, using `GRPC_TRACE='event_engine*'` will enable all flags that match that glob. It expands to:
* event_engine
* event_engine_client_channel_resolver
* event_engine_dns
* event_engine_endpoint
* event_engine_endpoint_data
* event_engine_poller
### A cleaner trace-logging macro in abseil logging format
If your goal is only to add log statements when the `fault_injection_filter` trace flag is enabled, you can use the macro:
```
GRPC_TRACE_LOG(fault_injection, INFO) << "Filtered:" << 42;
```
When the trace flag is enabled, the the log will show something like this:
```
I0000 00:00:1715733657.430042 16 file.cc:174] Filtered:42
```
----
Note: just like with the gpr_log to abseil logging conversion, the pre-existing trace logging usages can be replaced with the new tracing macro across multiple PRs.

The following attributes were completely unused:
- kOffset
- kIndex
- kSize
- kFilename
- kKey
- kValue
The following attributes were added but never programmatically accessed, and I've moved them into the status messages themselves, which is another step toward #22883:
- kErrorNo
- kTsiCode
- kWsaError
- kHttpStatus
- kOsError
- kSyscall
- kTargetAddress
- kRawBytes
- kTsiError

Also begin to eliminate `CallContext` in favor of just exposing `Call` - ultimately there's not really a need to introduce two types here, so I'm going to wind that idea back over a few PRs.
I've avoided making this an experiment as the changes required were quite structural.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK.
These changes have been made using string replacement and regex.
Will not be replacing all instances of CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only ones which are doable using very simple regex with least chance of failure will be replaced.
Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

It looks like we're settling on moving this functionality into the channel itself - so removing the filter makes sense (especially since it had some significant bugs)

This adds the following new targets:
- `channel`: A virtual interface for a channel.
- `legacy_channel`: A channel implementation that supports the filter stack and call v2.
- `channel_create`: A standalone function to create a channel.
- `server_interface`: A base class with a few accessor methods used in surface/call.cc.
- `server`: The actual server implementation.
- `api_trace`, `call_tracer`, `server_call_tracer_filter`, `call_finalization`: These were split out of `grpc_base` to avoid various dependency problems.
- `compression`: This is a combination of the previously existing `compression_internal` target and the compression code that was part of `grpc_base`.
