I'm fixing the ALTS/Envoy transport socket extension (which is currently
broken). Along the way, I'm trying to remove as many uses of gRPC
internals as possible (with the eventual goal of only relying on public
gRPC APIs and the alts_zero_copy_grpc_protector). To this end, I need to
remove the ExecCtx check in the alts_zero_copy_grpc_protector_create
function, so that Envoy can call into this function without needing to
create an ExecCtx.
The logic is straightforward: attempt to read the
`GRPC_ALTS_MAX_CONCURRENT_HANDSHAKES` environment variable and, if it
set to an integer, instantiate the handshake queues based on this
integer.
Based on go/grpc-alts-concurrent-handshake-cap.
This check only works if all handshake RPCs have an OK status, and it's
racey e.g. if the client is cancelling handshake RPCs (being when an RPC
is cancelled, termination of the RPC at the client is asynchronous from
termination at the server, so the client can resume the queue before the
server RPC completes).

* reviewer feedback
* first pass at excluding EventEngine test expansion
Also caught a few cases where we should not test pollers, but should
test all engines. And two cases where we likely shouldn't be testing
either product.
* end2end fuzzers to be fuzzed differently via EventEngine.

* Fix all lint errors in repo.
* Use strict buildifier by default
* Whoops. That file does not exist
* Attempt fix to buildifier invocation
* Add missing copyright
* Make generated code compile with -Wunused-parameters
-Wunused-parameters is turned on by -Werror -Wextra. gRPC code
generation creates header files with unused parameters. So let's modify
the generator to not generate code which will make -Wunused-parameters
unhappy.
* Fix unsigned vs signed comparisons and 32 bit string formats
Fix unsigned vs signed comparison warnings.
For 64 bit numbers printed in gRPC, the string formats assume that you
are running on a 64 bit machine. Use inttypes.h to make it portable.
Also, use size_t format strings for the same reason.
* Fix unaligned memory access
cost_entry_ptr has no alignment guarentees that ubsan can find. So it
fails the test with an alignment problem. Use memcopy to read the data
from the pointer to fix this.
* Fix undefined behavior with memcpy and memcmp
Passing in a 0 length piece of data and a null pointer is undefined
behavior. If the length is 0, don't pass it in. This fixes ubsan
failures.
* Clang-format
* Automated change: Fix sanity tests
