Changes -
* Add CMake build support to `grpcpp_otel_plugin`. Currently, we are only supporting the `find_package CONFIG` method for depending on `opentelemetry-cpp`.
* Since, `grpcpp_otel_plugin` is an extension of gRPC, it will not be built by default. To enable building of this target, a new CMake option `gRPC_BUILD_GRPCPP_OTEL_PLUGIN` is being added.
* Also add `CMakeLists.txt` to the otel example.
The `otel_plugin_test` can also be built through cmake but, for the CI to work, there are some additional changes. Those will be made in an upcoming PR.
Closes#36063

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`.
Add a config to experiments & rollouts to allow dependent experiments to
be flagged.
We're getting past the point where it's possible to reason about which
experiments need to be turned off if we disable some other experiment,
and so this provides some additional rollout safety.
Can be specified in both experiments and rollouts: experiments.yaml
makes the most sense and we should default to it, but rollouts.yaml lets
us put dependencies between internal & external dependencies internally
and that's gonna be a little useful.

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.

We have a bunch of experiments testing against core e2e - and this is
good for robustness, bad for CI times.
We also have a bunch of marginal but overall necessary fixtures in the
e2e suites - again good for robustness, bad for CI times.
We can eliminate some of the cross product though, and I think safely:
run experiments on a broad range of suites, but not *ALL* the suites,
and get a bunch of our CI time back.
Here I introduce an environment variable: `GRPC_CI_EXPERIMENTS` that's
set when running bazel @experiment= configs, cleared otherwise (so we
can still execute those tests directly when necessary). When that env
var is set we filter out a bunch of suites from the test configurations.

Note that the plugin is still under `grpc::internal` namespace and not
under `experimental` intentionally.

~Something about the additional load from #33374 has caused some
entirely unrelated ios tests to fail sporadically. I'd prefer not to
roll back that however as it's discovered real bugs that had been
previously masked.~
These tests have been failing sporadically for some time.
We can track these on the daily flakiness reports, but whilst we
investigate let's just universally mark them as flaky so we don't
confuse folks trying to submit.
The PR does the following:
* Splits the single experiments.yaml file into two files:
experiments.yaml and rollouts.yaml.
* The experiments.yaml will now only include experiment definitions. The
default values of the experiments must now be specified in rollouts.yaml
* Removes the 'release' default value because it is not used.
* Adds an additional_constraints character string to ExperimentMetadata.
* Introduces a hook in src/core/lib/experiments/config.h to allow
registering arbitrary experiment constraint validation callbacks. These
callbacks would take an ExperimentMetadata object as input and return
the correct value to use for an experiment subject to additional
constraints.
This will change behavior for tests that have experiments enabled on
them to always have the flaky bit on.
In doing so, we'll get the usual failure reporting we do in the internal
chat bot, but allow PRs to pass even if an experiment isn't 100% passing
yet - reducing friction slightly for landing bigger experiments.

The PR also creates a separate BUILD target for:
- chttp2 context list
- iomgr buffer_list
- iomgr internal errqueue
This would allow the context list to be included as standalone
dependencies for EventEngine implementations.
* Revert "Revert "Add support for systemd socket activation (#30485)" (#31617)"
This reverts commit 867dc6cae2.
* Add checks to unix tests
* Ran generate_projects.sh and fixed styling in test
* Fix variable in unit test
* Use reinterpret_cast in test
* Rebase and fix sanity failures
