This eliminates the need for the `grpc_cc_proto_library` bazel BUILD rule introduced in #37863.
To make this work, I had to upgrade several bazel dependencies and apply a patch to rules_go to work around https://github.com/bazelbuild/bazel/issues/11636.

Add a ValidateCredentials API to the TLS certificate provider interface. A user can call this API to check that the credentials currently held by the certificate provider instance are valid. The definition of "valid" depends on provider that is being used. For the static data and file watcher providers, "valid" means that the credentials consist of valid PEM.
~Currently there is no check to ensure that credentials consist of valid PEM blocks before a TLS handshake commences. This PR creates a static factory for FileWatcherCertificateProvider (and marks the constructor as deprecated) which performs this validation check. The analogous work for StaticDataCertificateProvider will be done in a follow-up PR.~

[Gpr_To_Absl_Logging] Remove gpr_log. Adding absl LOG wrappers
List of changes in this PR
1. Replacing all instances of gpr_log in PHP and RUBY with the new absl wrapper APIs. The replacement mapping is given below
gpr_log(GPR_ERROR, ...)
=> grpc_absl_log_error
gpr_log(GPR_INFO, ...)
=> grpc_absl_log_info - Printing a simple message
=> grpc_absl_log_info_int - Printing a message and a number
=> grpc_absl_log_info_str - Printing 2 strings.
gpr_log(GPR_DEBUG, ...)
=> grpc_absl_vlog - Printing a simple message
=> grpc_absl_vlog_int - Printing a message and a number
=> grpc_absl_vlog_str - Printing 2 strings.
Adding grpc_absl_vlog2_enabled() check around gpr_log(GPR_DEBUG, ...)
2. src/python/grpcio_observability/grpc_observability/observability_util.cc One instance of gpr_log to absl LOG replacement was missed earlier. Fixing that.
3. Deleting deprecated gpr stuff : gpr_log_severity , GPR_DEBUG , GPR_INFO , GPR_ERROR , gpr_log .
4. Adding new APIs for Ruby and PHP. These APIs are very simple wrappers around absl.
5. Removing the legacy functions in platform specific log.cc files. These files are safe to delete now.
6. Fixing the allow list in banned_functions.py . This makes sure that these new wrappers don't get used all over the place by everyone. We carefully only allow list the PHP and RUBY files and allow the use of these wrappers. Everywhere else - using these wrappers should fail Sanity Tests.

Add validation of the `Audience` cluster metadata type, as per gRFC A83 (https://github.com/grpc/proposal/pull/438).
I had previously changed the metadata to be represented as JSON in #37468. However, while working on the GCP Authentication filter implementation, I realized that that's not an ideal representation, because it would have required us to validate the JSON on a per-RPC basis, which would be bad for performance. So I've changed the representation of metadata to be an abstract type, and we now store the `Audience` metadata as a simple string. I've also moved metadata into its own type with its own validation code, so that in the future we can use it in places other than CDS (many xDS resource types have metadata fields).
While I was at it, I also add some helper functions for validating the `UInt32Value` and `UInt64Value` wrapper protos.
Closes#37566

Some applications cannot avoid the dependency on `//:grpc++_reflection` because it is buried by several infrastructural layers. For binaries that need to implement their own reflection server via generic handlers, this makes accepting request impossible as they will instead be handled by the default reflection server added by the server reflection plugin.
It would not be feasible to implement this as a build define because this binary is depended upon by many applications and buried beneath several layers of infrastructure.
Further, we cannot use the flag to control whether or not the plugin is installed as the plugin is installed at static initialization time, meaning that flags have not been parsed yet. Instead, we simply disable the functionality of the plugin with this flag.

PiperOrigin-RevId: 652397141
Instead of passing the transport byte counts back up through the filter
stack to be reported to the `CallTracer`, we now have the transport
pass the transport byte counts directly to the `CallTracer` itself.
This will eventually allow us to avoid unnecessarily storing these byte
counts in cases where no `CallTracer` actually cares about the data, which
will reduce per-call memory. (In the short term, it actually increases
memory usage, but we can separately do some work to avoid the memory
usage in the transport by removing the `grpc_transport_stream_stats`
struct from the legacy filter API.)
This is a prereq for supporting `CallTracer` in the new call v3 stack,
which does not include the transport byte counts as part of the
receieve-trailing-metadata hook, unlike the legacy filter stack.
This change is controlled by the `call_tracer_in_transport` experiment,
which is enabled by default.
As part of this experiment, we also fix a couple of related bugs:
- On the client side, the chttp2 transport was incorrectly adding
annotations to the parent `ClientCallTracer` instead of the
`CallAttemptTracer`.
- The OpenCensus `ServerCallTracer` was incorrectly swapping the values
of sent and received bytes.
PiperOrigin-RevId: 650728181
This allows CallTracers to be created with parameters dictated by
channel args.
For the moment, I've used the EventEngine `EndpointConfig` API to expose
the channel args here, so as to avoid directly exposing
`grpc_core::ChannelArgs`. We should determine a better API here before
we de-experimentalize the stats APIs.
Also add an experiment to be used in a subsequent PR.

Previously, metadata mutations were made by the picker directly, which meant that they would be applied even if the channel winds up discarding the pick due to the returned subchannel having been disconnected by the time the pick result is returned. This changes the API such that pickers return metadata mutations along with the pick result, so that the mutations won't get applied unless the pick result is actually used.

- use `absl::string_view` instead of `const char*` for handshaker names
Also pass acceptor via `HandshakerArgs` instead of as a separate parameter.

This change brings up the direct channel, and inproc promise based transports.
This work exposed a bug that was very difficult to fix with the current call_filters.cc implementation, so I've substantially revamped that - instead of having a pipe-like object per call element, we now have a big ol' combined state machine for the entire call. It's a touch more code, but substantially easier to reason about individual cases, so I much prefer this form (it's also a slight memory improvement: 12 bytes total to track call state, and 10 of those are wakeup bitmasks...).

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.

Usage: `bazel build --config=clang-cl --build_tag_filters=-no_windows :all`
The highlight, for me anyway: thread safety annotation checking can now be done on Windows-only code.
clang-cl's interpretation of `-Wall` differs from that of clang on linux. This PR uses the set of warnings enabled on linux, and whittles down the list until all builds pass. I left comments in `copts.bzl` describing the warnings, many of which can be removed with targeted code cleanups.
