This commit upgrades gRPC to protobuf v25.0 and makes some fixes to
account for upb changes. One major change is that upb has been merged
into the protobuf repo, so we can now drop the separate `@upb`
dependency. Another is that `.upb.c` files no longer exist and there are
new `.upb_minitable.h` and `.upb_minitable.c` files. The longer
filenames exceeded a Windows restriction, so to work around that I
renamed the `upb-generated` directory to just `upb-gen`, and likewise
for `upbdefs-generated`.
Currently it is very easy to use the `TlsCredentialsOptions` in such a
way that it produces a memory leak. For example, the code block
```
{
TlsCredentialsOptions options;
}
```
produces a memory leak. This PR fixes up the ownership bugs in this
class and its `grpc_tls_credentials_options`, the C-core analogue.
Add TcpTracer interface for TCP instrumentation. It takes no gRPC
dependencies for use in external TCP implementations. Also add
HttpAnnotation for HTTP transport instrumentation using CallTracer.

- Added ARM64 to MacOS to be clear about the recent Apple Silicon
support.
- Removed x86 from MacOS as x86 is no longer used for Apple.
- Changed ARM to ARM64 for Linux as Foundational-cxx-support only
support ARM64 although gRPC is still working on ARM32.
Reverse dependency edge, so instead of saying `logging_filter _after_
otel`, instead say `otel _before_ logging_filter` - since this doesn't
inadvertently bring otel into builds where it's unnecessary.
Required moving filter class definitions into the header - which mirrors
all other filters, so I think this is fine.
Also required removing the bespoke visibility rules on logging_filter -
which also seems relatively fine (the defaults limit to grpc usage, and
it's hard to see a firm requirement for tighter visibility that that).
Ditch the old priority scheme for ordering filters, instead explicitly
mark up before/after constraints.

The basic APIs for the CRL Reloading features.
This adds external types to represent CRL Providers, CRLs, and
CertificateInfo.
Internally we will use `CrlImpl` - this layer is needed to hide OpenSSL
details from the user.
GRFC - https://github.com/grpc/proposal/pull/382
Things Done
* Add external API for `CrlProvider`, `Crl`, `CertInfo` (`CertInfo` is
used during CRL lookup rather than passing the entire certificate).
* Add code paths in `ssl_transport_security` to utilize CRL providers
* Add `StaticCrlProvider`
* Refactor `crl_ssl_transport_security_test.cc` so it is more extensible
and can be used with providers
@stanley-cheung noticed a bug where CSM labels were not being added on
metrics if the peer was not also CSM Observability enabled.
This PR fixes the behavior to add in the local labels in this case, as
well as add the remote workload type label with the value of unknown.

There's an ongoing discussion on whether we should have API to disable
default metrics. Removing this API till we have a decision on that.
I'm keeping the internal API for enabling/disabling metrics on the OTel
plugin for now, just not exposing it publicly.
Changes -
* CsmObservability doesn't need `SetTargetSelector`. Removed it.
* Added missing plumbing of `ServiceMeshLabelsInjector` in
`CsmObservability` to actually do the metadata exchange.

Changes -
* Use `grpc-c++` as the meter name and the proper version string when
creating the meter for OTel
* setting metric description and unit. (Pointed out by @DNVindhya )
Changes -
* Remove `csm.remote_workload_pod_name` and
`csm.remote_workload_container_name`.
* Add `csm.remote_workload_name`, the value for which is sent through
MetadataExchange, from the `CSM_WORKLOAD_NAME` env var. (Note that this
is not added in local labels.)
* Add a local `csm.canonical_service` (@markdroth, please verify the key
that we want here) that is read from `CSM_CANONICAL_SERVICE_NAME` env
var, and we continue to send it over via MetadataExchange
This reverts commit 2db446aa9a.

I've added channel args to `CreateNewServerCallTracer` on the
`ServerCallTracerFactory`.
The motivation is for CSM Observability where the OTel plugin will be
configured to only do stats on servers which are xDS enabled, so I plan
to check this via channel args.
In the future, with the new scopes for metrics, I think I'll be able to
change this to only check once per server or server connection instead
of per call.

@ctiller PTAL for core configuration changes. I converted the type from
std::function to absl::AnyInvocable. Do you think the functor in
RegisteredBuilder should be callable just once or multiple times?

Changes -
1) Change local mesh labels to not be reported on 'started' metrics at
all (even those that we know about) to be consistent. (Since xDS labels
atleast on the server side would not be available on started metric.)
2) Add mesh_id as a local label that is populated by reading the xDS
bootstrap. As part of this, also added a minimal xds bootstrap parsing
logic.

A new metadata type `x-envoy-peer-metadata` is being introduced. We
don't have a better way to do this at the moment compared to just adding
it in `metadata_batch.h`.
The GSM Observability plugin uses this metadata to send topology
information to peers in the form of serialized and base64 encoded
`google::protobuf::Struct`. The individual keys being used inside the
struct are subject to change.

We added this as an exploratory measure for a customer that thought they
were using open census (this turned out to be emphatically false).
Remove it since it's probably not how we ultimately want to do this, and
wait for something better to come along.

This PR is mainly a set of improvements that allow the C++ Alarm to be
migrated away from legacy iomgr. It cannot be landed without significant
speedup, due to third-parties relying on a fast path for immediate timer
execution with deadlines <= now.
Previous EventEngine performance of bm_alarm, compared to baseline iomgr
timers: *0.014%*
This PR: *2.5%*
Regarding previous failures to land this change: The cloud libraries
team agreed to reduce the amount of stress in their alarm stress test

I'm fairly certain that this path should be non-blocking (and making it
so makes the promise based code far more tractable).
This moves the blocking behavior into the blocking server_cc.cc function
that calls `grpc_server_shutdown_and_notify` instead of in that
non-blocking function.
