In gh-120009 I used an atexit hook to finalize the _datetime module's static types at interpreter shutdown. However, atexit hooks are executed very early in finalization, which is a problem in the few cases where a subclass of one of those static types is still alive until the final GC collection. The static builtin types don't have this probably because they are finalized toward the end, after the final GC collection. To avoid the problem for _datetime, I have applied a similar approach here.
Also, credit goes to @mgorny and @neonene for the new tests.
FYI, I would have liked to take a slightly cleaner approach with managed static types, but wanted to get a smaller fix in first for the sake of backporting. I'll circle back to the cleaner approach with a future change on the main branch.
Add __all__ to the following modules:
importlib.machinery, importlib.util and xml.sax.
Add also "# noqa: F401" in collections.abc,
subprocess and xml.sax.
* Sort __all__; remove collections.abc.__all__; remove private names
* Add tests
Add a `Path.copy()` method that copies the content of one file to another.
This method is similar to `shutil.copyfile()` but differs in the following ways:
- Uses `fcntl.FICLONE` where available (see GH-81338)
- Uses `os.copy_file_range` where available (see GH-81340)
- Uses `_winapi.CopyFile2` where available, even though this copies more metadata than the other implementations. This makes `WindowsPath.copy()` more similar to `shutil.copy2()`.
The method is presently _less_ specified than the `shutil` functions to allow OS-specific optimizations that might copy more or less metadata.
Incorporates code from GH-81338 and GH-93152.

Add dedicated subsection for `pathlib.Path.touch()`, `mkdir()`,
`symlink_to()` and `hardlink_to()`. Also note that `open()`, `write_text()`
and `write_bytes()` are often used to create files.

Tools such as ruff can ignore "imported but unused" warnings if a
line ends with "# noqa: F401". It avoids the temptation to remove
an import which is used effectively.
Remove wheeldata from both sides of the `assertEqual`, so that we're
*actually* ignoring it from the test set.
This test is only making assertions about the source tree, no code is
being executed that would do anything different based on the value of
`WHEEL_PKG_DIR`.
The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation). That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters. This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).
