Some systems have the definitions of the mask bits without having the
corresponding members in struct statx. Add configure checks for members
added after Linux 4.11 (when statx itself was added).
Android has Linux's statx, but MACHDEP is "android" on Android, so
configure doesn't check for statx on Android. Base the check for statx
on ac_sys_system instead, which is "Linux-android" on Android, "Linux"
on other Linux distributions, and "AIX" on AIX (which has an
incompatible function named statx).
stx_atomic_write_unit_max_opt was added in Linux 6.16, but is controlled
by the STATX_WRITE_ATOMIC mask bit added in Linux 6.11. That's safe at
runtime because all kernels clear the reserved space in struct statx and
zero is a valid value for stx_atomic_write_unit_max_opt, and it avoids
allocating another mask bit, which are a limited resource. But it also
means the kernel headers don't provide a way to check whether
stx_atomic_write_unit_max_opt exists, so add a configure check.
Adds tooling to generate and test an iOS XCframework, in a way that will also facilitate
adding other XCframework targets for other Apple platforms (tvOS, watchOS, visionOS and
even macOS, potentially).

With https://github.com/llvm/llvm-project/pull/150201 being merged, there is
now a better way to generate the Emscripten trampoline, instead of including
hand-generated binary WASM content. Requires Emscripten 4.0.12.
A runtime check is needed to support cross-compiling.
Remove the _Py_NORMALIZE_CENTURY macro.
Remove _pydatetime.py's _can_support_c99.

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.
Basic support for pyrepl in Emscripten. Limitations:
* requires JSPI
* no signal handling implemented
As followup work, it would be nice to implement a webworker variant
for when JSPI is not available and proper signal handling.
Because it requires JSPI, it doesn't work in Safari. Firefox requires
setting an experimental flag. All the Chromiums have full support since
May. Until we make it work without JSPI, let's keep the original web_example
around.
