This is a prerequisite change to start supporting Bazel 7. Changes are
- Disabled bzlmod which Bazel 7 begins to enable by default. This eventually needs to be done to support bzlmod but not now.
- Upgraded some bazel rule dependencies which are required to support Bazel 7.
- Using Python 3 explcitly as Bazel 7 begins to reject Python 2.
Note that this isn't enough to enable Bazel 7 by default and another PR will follow for that.
Closes#35374

This is to address too many warnings coming from upb 24.x
```
In file included from external/upb/upb/mini_table/field.h:32:

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

This maybe used to quickly verify the code coverage of a modified test
locally (e.g. fuzzer).
Example:
```
# Build and run target; the raw profile will be written to $LLVM_PROFILE_FILE when the program exits
$ bazel build --config=dbg --config=fuzzer_asan --config=coverage //test/core/end2end/fuzzers:api_fuzzer
$ LLVM_PROFILE_FILE="api_fuzzer.profraw" bazel-bin/test/core/end2end/fuzzers/api_fuzzer test/core/end2end/fuzzers/api_fuzzer_corpus/*
# Create coverage report
$ llvm-profdata-14 merge -sparse api_fuzzer.profraw -o api_fuzzer.profdata
$ llvm-cov-14 report ./bazel-bin/test/core/end2end/fuzzers/api_fuzzer --instr-profile=api_fuzzer.profdata
```
Sample report:

One trick is that the binary needs to be statically linked, e.g. specify
`linkstatic = 1` on the BUILD target.
See https://clang.llvm.org/docs/SourceBasedCodeCoverage.html for more
info.

Initial PR to establish a bazel dependency on
https://github.com/google/fuzztest, with which I'm planning on basing a
hardening program.
Casting a relatively wide net with reviewers: I'm genuinely interested
in feedback building up the docs, and general ergonomics of this change.
I've located relevant files in the `fuzztest/...` directory. The tests
only build with the `--config fuzztest` bazel argument for now (because
of needing C++17), so locating them separately keeps `bazel test
test/...` working as it does today. In a few years time, when we adopt
C++17, we'll be able to rationalize the test directories a little bit.
We'll need to add some kokoro jobs (maybe with this PR?) to execute the
relevant tests.

With the `--copt="-std=c++14"` setting in the bazel.rc file as it is
today, MSVC builds have complained for every cc file:
```
cl : Command line warning D9002 : ignoring unknown option '-std=c++14'
```
This adds thousands of lines of noise to Windows builds, and hides
useful warnings. Using the `/std:c++14` flag on MSVC (and clang-cl) gets
us the desired result.

* Only hold lock during Close once
* Create separate job for fork test
* Bump up gdb timeout
* Format
* [cleanup] Remove profiling timers
- nobody has used this system in years
- if we needed it, we'd probably rewrite it at this point to be something more modern
- let's remove it until that need arises
* fix
