The bytes shorthand was removed in PEP 688:
https://peps.python.org/pep-0688/#no-special-meaning-for-bytes

I also remove the reference to `collections.abc.ByteString`, since that
object is deprecated (#91896) and has different semantics (#102092)

Replaces our built-in SHA3 implementation with a verified one from the HACL* project.

This implementation is used when OpenSSL does not provide SHA3 or is not present.

3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project.

Stop de-duplicating results in `_RecursiveWildcardSelector`. A new
`_DoubleRecursiveWildcardSelector` class is introduced which performs
de-duplication, but this is used _only_ for patterns with multiple
non-adjacent `**` segments, such as `path.glob('**/foo/**')`. By avoiding
the use of a set, `PurePath.__hash__()` is not called, and so paths do not
need to be stringified and case-normalised.

Also merge adjacent '**' segments in patterns.

Re-arrange `pathlib.Path` methods in source code. No other changes.

The methods are arranged as follows:

1. `stat()` and dependants (`exists()`, `is_dir()`, etc)
2. `open()` and dependants (`read_text()`, `write_bytes()`, etc)
3. `iterdir()` and dependants (`glob()`, `walk()`, etc)
4. All other `Path` methods

This patch prepares the ground for a new `_AbstractPath` class, which will
support the methods in groups 1, 2 and 3 above. By churning the methods
here, subsequent patches will be easier to review and less likely to break
things.

This is a pre-requisite for a per-interpreter GIL.  Without it this change isn't strictly necessary.  However, there is no real downside otherwise.

Py_MOD_PER_INTERPRETER_GIL_SUPPORTED is a new supported value for Py_mod_multiple_interpreters, added in gh-104205.

The locale module reference was introduced by 932ff83 in 2013,
and rendered unused by 710e826 (gh-23050) in 2020.

Improve performance of `pathlib.Path.absolute()` and `cwd()` by joining paths only when necessary. Also improve
performance of `PurePath.is_absolute()` on Posix by skipping path parsing and normalization.

Replace `self._canvas` and `self.scanvas`, both bound to `canvas`,
