gh-127266: avoid data races when updating type slots (gh-131174)
...
In the free-threaded build, avoid data races caused by updating type slots
or type flags after the type was initially created. For those (typically
rare) cases, use the stop-the-world mechanism. Remove the use of atomics
when reading or writing type flags. The use of atomics is not sufficient to
avoid races (since flags are sometimes read without a lock and without
atomics) and are no longer required.

We replace it with _Py_GetMainModule(), and add _Py_CheckMainModule(), but both in the internal-only C-API. We also add _PyImport_GetModulesRef(), which is the equivalent of _PyImport_GetModules(), but which increfs before the lock is released.
This is used by a later change related to pickle and handling __main__.

gh-132983: Introduce compression package and move _compression module (GH-133018)
...
* Introduces `compression` package for https://peps.python.org/pep-0784/
This commit introduces the `compression` package, specified in PEP 784
to re-export the `lzma`, `bz2`, `gzip`, and `zlib` modules. Introduction
of `compression.zstd` will be completed in a future commit once the
`_zstd` module is merged.
This commit also moves the `_compression` private module to
`compression._common._streams`.
* Re-exports existing module docstrings.
