The Python comparison protocol requires that if an object doesn't know how to
compare itself to an object of a different type, it returns NotImplemented
rather than False. The interpreter will then try performing the comparison using
the other operand. This translates, for protos, to:
If a proto message doesn't know how to compare itself to an object of
non-message type, it returns NotImplemented. This way, the interpreter will then
try performing the comparison using the comparison methods of the other object,
which may know how to compare itself to a message. If not, then Python will
return the combined result (e.g., if both objects don't know how to perform
__eq__, then the equality operator `==` return false).
This change allows one to compare a proto with custom matchers such as mock.ANY
that the message doesn't know how to compare to, regardless of whether
mock.ANY is on the right-hand side or left-hand side of the equality (prior to
this change, it only worked with mock.ANY on the left-hand side).

GetOptions on fields (which parse the _serialized_options) will be called for the first time of parse or serialize instead of Build time.
Note: GetOptions on messages are still called in Build time because of message_set_wire_format. If message options are needed in descriptor.proto, a parse error will be raised in GetOptions(). We can check the file to not invoke GetOptions() for descriptor.proto as long as message_set_wire_format not needed in descriptor.proto.
Other options except message options do not invoke GetOptions() in Build time

This fixes Python/C++ and upb, and pushes the buggy behavior to pure python. There, it's very difficult to handle options on the bootstrapped proto with the current architecture. Future changes will attempt to address this more isolated issue.

This proto is only used in C++ tests, and doesn't need to be built in python. Python doesn't support editions yet, so we should just remove it for now. This also fixes some other issues with setup.py where tests fail.

When build a FileDescriptorProto into pool, FieldDescriptorProto.type may not set if type_name is set. This only add tests. UPB python Fix has been submit in other change
PiperOrigin-RevId: 554516745
Use the default generated pool for some message factory tests. Use a new descriptor
pool each time may turns out flake refleck test -- garbage collectors aren't
very predictable.
For blaze test third_party/py/google/protobuf/internal:message_factory_test_python_protos --runs_per_test_detects_flakes --runs_per_test=1000 --copt=-DPy_DEBUG
There were 30-50 failures before the change. Now tests are passing

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.
