Allow the --enable-pystats build option to be used with free-threading. The
stats are now stored on a per-interpreter basis, rather than process global.
For free-threaded builds, the stats structure is allocated per-thread and
then periodically merged into the per-interpreter stats structure (on thread
exit or when the reporting function is called). Most of the pystats related
code has be moved into the file Python/pystats.c.
Move the public PyUnicodeWriter API and the private _PyUnicodeWriter
API to a new Objects/unicode_writer.c file.
Rename a few helper functions to share them between unicodeobject.c
and unicode_writer.c, such as resize_compact() or unicode_result().
Expose `_PyUnicode_IsXidContinue/Start` in `unicodedata`:
add isxidstart() and isxidcontinue() functions.

The `Modules/hashlib.h` helper file is now removed and split into multiple files:
* `Modules/_hashlib/hashlib_buffer.[ch]` -- Utilities for getting a buffer view and handling buffer inputs.
* `Modules/_hashlib/hashlib_fetch.h` -- Utilities used when fetching a message digest from a digest-like identifier.
Currently, this file only contains common error messages as the fetching API is not yet implemented.
* `Modules/_hashlib/hashlib_mutex.h` -- Utilities for managing the lock on cryptographic hash objects.
`_datetime` is a special module, because it's the only non-builtin C extension that contains static types. As such, it would initialize static types in the module's execution function, which can run concurrently. Since static type initialization is not thread-safe, this caused crashes. This fixes it by moving the initialization of `_datetime`'s static types to interpreter startup (where all other static types are initialized), which is already properly protected through other locks.
Extension builders must specify Py_GIL_DISABLED if they want to link to the free-threaded builds.
This was usually the case already, but this change guarantees it in all circumstances.
