A bug was found during code review that didn't trigger any test failure
The fast TDP entry did not have the index in the aux_idx field.

The validation is done at the highest point so if a sub message is what
goes over the limit it is caught at the outer message, thus reducing the
impact on the serialization code.

The code that loads descriptors calls absl::CUnescape() to parse the escape sequences. Prior to this CL, we were not checking the return value of this call, effectively allowing the invalid data to be loaded.
If a user is compiling a .proto file, invalid escapes will be caught earlier in the compiler pipeline, and this check will be unnecessary. The only time this is an issue is when a descriptor has been constructed manually and is loaded into the runtime.
This bug manifested as an MSAN failure in a fuzz test, because in the error case absl::CUnescape() will return a string where some of the characters are uninitialized.

Add a helper to put the logic in one place in the file.
Ensure all places that read messages also do the 2GB check for message size.

Fix exit code on git commit which was preventing force-push and tagging from running even though these should work without a new commit. An empty commit is probably clearer anyways to show that sync has happened.

If a change is committed while we're regenerating stale files, we should just bail and let the next job handle the refresh.

Add the objects to the object graph and balance the retain count before
doing the parsing. This ensure if an error is hit (and a throw happens),
the object(s) won't be leaked.
Parsing will always mutate the graph, so yes this includes more mutations
in failure cases, but other fields could always be modified before the
bad data is encountered. But even then, that edge case *only* apples to api
users that are explicitly *merge* (-mergeFrom...), the majority of the calls
are to +parseFromData:error:, so the entire graph is released on failure.

The last attempted (rolled back) resulted in changes in visible behavior:
- It consumed a recursion depth on the input stream (wrong)
- It resulted in different error codes for some malformed/truncated data.

Unconditional update of isMutable causes data races for
LazyStringArrayList::EMPTY_LIST that is used as the default value
for protobuf fields.
Not writing to it unconditionally may also improve performance
by reducing contention for the presumably widely shared EMPTY_LIST object.

Chocolatey doesn't support any caching, so we're moving back to downloading the exe directly. This issue is responsible for a 5-10% flake rate in our windows cmake builds

This fixes some relatively harmless flakiness in our post-submit. If two commits are made within ~5 minutes of each other, the `git push` command will fail because the git workspace isn't up to date.

Bazel has a 2 minute timeout for their internal `xcrun` call, which can be exceeded on our github runners about 5% of the time. This leads to flakes and opaque errors, but is a one-time cost. Subsequent xcruns finish in seconds, so we can just do an initial call w/o a timeout before running Bazel.
With this change our total flake rate drops from ~30% to nearly 0% for our full suite of tests
