PEP634 introduces structural pattern matching. This works out of the box for most parts of protobuf messages, but fails for sequence matching (defined in https://peps.python.org/pep-0634/#sequence-patterns). This is caused by the underlying containers missing the newly introduced Py_TPFLAGS_SEQUENCE flag (see 069e81ab3d).
This simply adds the flag, making the following fall into the first case:
```
message = test_pb2.TestMessage(int_sequence=(1, 2, 3))
match message:
case test_pb2.TestMessage(int_sequence=(1, *rest)):
print(f"message.int_sequence is a seq starting with 1, ending in {rest}")
case _:
print(f"No case on 'int_sequence' matched! Value: {message.int_sequence}")
```

This is a copy of https://github.com/protocolbuffers/protobuf/pull/12431
but with the ifdef logic reversed. The original PR could not kick off our
CI tests because it wasn't branched directly from repo main.
Thanks to Tom Gillespie for the original PR.

There were two bugs here: Python was incorrectly mandating that a required
field be set during assignment, and it was also incorrectly assuming a non-NULL
return from an internal function call.

No need for a loop that that calls tryConsumeString or tryConsumeByteString repeatedly, since ConsumeByteString already loops itself.

In 21.x, depending on "//python:well_known_types_py_pb2" provided a transitive dependency to `compiler/plugin.proto`. That dependency was incorrectly removed for 22.x.
In order to flip the flag, all downstream projects should be adapted. However, it is hard to fix them all if there are constant regressions. Adding it to the CI will ensure that once the project can build with incompatible_disallow_empty_glob it can keep building like that.

This deletes our old branches of internal Abseil code in favor of their newly open-sourced library. Notably, this removes the ability to turn CHECK crashes into exceptions.

This bumps us to gcc 6 (rather than 4.8), which fully supports C++14, and migrates the Python tests to our Bazel-based system. C#, PHP, and Ruby will remain on CMake + alternate build system for now.
