The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

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.

First step in the modernization of our RBE stack (see
go/rbe-tech-debt-notes).
- Get rid of the deprecated rbe_autoconfig and start using
[rbe_configs_gen](https://github.com/bazelbuild/bazel-toolchains#rbe_configs_gen---cli-tool-to-generate-configs)
+ check in the generated toolchain configs.
- Switch from marketplace.gcr.io/google/rbe-ubuntu16-04 to
marketplace.gcr.io/google/rbe-ubuntu18-04 (this image is still not owned
by us, but at least it's newer and demonstrates how a switch to a newer
docker image is done).
- provide script for generating the linux RBE toolchain configs.
- cleanup RBE configuration in the bazelrc files used for remote build
* Ensure results of Bazel distribtests are not cached across versions.
* Please the shellcheck overlords
* Try to use action env to invalidate cache
* Change placement of Bazel version check
* Review comments
* Add version test to build step as well
GitHub has changed their releases pages to not use full server-side
rendering. Instead, individual artifacts are now fetched as a separate
HTML chunk via javascript. This defeats the previous method.
Instead, we now rely on the URI of the 301 redirect to indicate the
identity of the latest release.
* update win RBE docker image and toolchain
and switch win RBE builds to using it.
* delete legacy RBE windows toolchain config
* switching to VS2019 makes #28544 obsolete
* Add bazel cpp distribtest for grpc_cc_library
* Add new directory to bazelignore
* Try changing to workspace differently
* Debug cd
* Fix bazel wrapper
* Yet more debug
* Try again
* Clean up
* Sanity fixes
* Run per-language distribtests even if overall build fails
* Make repo globally buildable
* Add initial distrib test script
* Add test script
* Support multiple versions
* Split out a separate latest version test
* Integrate with kokoro
* make tools/bazel version overridable
* added simplified test_single_bazel_version.sh
* cleanup .bazelignore
* only test 3.x and 4.x
* always test all the bazel versions
* revert unnecessary changes
* revert unnecessary changes
* fix shellcheck error
