`ProtoBitGen` provides a random number generator that returns values directly from fuzzer selected values, which allows us to test-into random selection algorithms deterministically.
Since the list of values provided by the fuzzer is limited, we need a fallback implementation. Previously we'd used something that was very correlated, and some of the distribution algorithms get into a very slow convergence mode when we do that (so we repeatedly return the same value for billions of iterations and cause timeouts in fuzzers).
Instead, when we run out of fuzzer supplied values, seed an mt19937 generator with the fuzzer selected values and use that from there on. Said generator will then produce values deterministically (for a given fuzzer input), but with a better distribution to allow convergence for fiddly algorithms.

As announced in https://discourse.llvm.org/t/clang-16-notice-of-potentially-breaking-changes/65562, clang 16 defaults `-Wincompatible-function-pointer-types` to be on. This causes a number of hard errors due to implicit conversions between `void *` and `void`, such as:
```

This commit fixes these pointer types using wrapper functions where necessary.

Fixes#30385 for C++/cmake.
Add a `gRPC_DOWNLOAD_ARCHIVES` switch that is on by default but can be disabled for environments building without Internet connectivity.
Passes build tests:
```
$ python tools/run_tests/run_tests.py -l c++ --build_only
PASSED: tools/run_tests/helper_scripts/build_cxx.sh [time=7116.3sec, retries=0:0SUCCESS: All tests passed
=== run_tests.py DEBUG INFO ===
command: "tools/run_tests/run_tests.py -l c++ --build_only"
===============================
$
```
And tested in a Docker container with `eth0` down to ensure we can now build when `-DgRPC_DOWNLOAD_ARCHIVES="OFF"` is passed to cmake.

`GPR_BACKWARDS_COMPATIBILITY_MODE` was devised to support old Linux kernel with old glibc but gRPC is now expected to support glibc 2.17 and later (2.17 is derived from the oldest but supported Linux distro, CentOS 7). Effectively, gRPC doesn't need `GPR_BACKWARDS_COMPATIBILITY_MODE` anymore. Hence, let's remove it.
gRPC Python and Ruby that distribute binary artifacts already began to use `manylinux` environment dealing with this issue in a better way so they don't need this flag anymore.

This PR is required in order to upgrade to the `master` branch version of protobuf. To do this, we upgrade to the latest version of `rules_python` by:
- Adding in explicit dependencies on all PyPi Bazel test dependencies
- Resolving the circular dependency this creates for `xds-protos` by giving it a Bazel build
- Generating the Python code for `xds-protos` as part of `generate-projects.sh` since doing so directly in Bazel would be highly fragily, dependent on many other projects' Bazel builds

A few improvements to the promise context system (more coming)
Allow subclassed contexts:
If we have multiple different kinds of a base context, allow `GetContext<Derived>()` to mean `down_cast<Derived*>(GetContext<Base>())` everywhere for brevity.
Allow custom context lookup:
For a base context type, allow customization of how that context is looked up.
These two together allow:
1. normalization of activity lookup and context lookup to the same syntax (so we can write `GetContext<Activity>()` everywhere now
2. Party & Activity to share a context, so that anywhere we need to do a party specific operation we can write `GetContext<Party>()->...` and safely know that it's the current activity *and* it's a party.

Only call constructors when absolutely necessary (empty trivially constructible types don't need construction!!)
Similarly for destructors, if the destructor is trivial it means C++ will do no work destructing it... let's not even do the virtual function call to get there.
(also fix a bug where we weren't calling this stuff anyway, and add a test that would have caught that)

We've been trying to upgrade Cmake to 3.13 or later as OSS policy bumped it. But we couldn't as Android has a weird linker error with Cmake 3.18 (you can see the error from https://github.com/grpc/grpc/pull/34331) This PR instead upgrades it to use 3.22 for Android test.

The `grpc_channel_args` is retained on the Ruby object and used for recreating the channel after forking in
grpc_rb_channel_maybe_recreate_channel_after_fork(). Previously, the key for each argument was taken from a Ruby string directly, which could be invalidated if the Ruby string is modified or moved by the GC. Duplicate the string for the key instead, so we own it.
