When Python build is optimized with GCC using PGO, use
-fprofile-update=atomic option to use atomic operations when updating
profile information. This option reduces the risk of gcov Data Files
(.gcda) corruption which can cause random GCC crashes.
* Drop DOUBLE_IS_ARM_MIXED_ENDIAN_IEEE754 macro.
* Use DOUBLE_IS_BIG/LITTLE_ENDIAN_IEEE754 to detect endianness of
float/doubles.
* Drop "unknown_format" code path in PyFloat_Pack/Unpack*().

* introduce executable specific linker flags
Add PY_CORE_EXE_LDFLAGS and EXE_LDFLAGS which stores executable specific
LDFLAGS, replacing PY_CORE_LDFLAGS for building
executable targets.
If PY_CORE_EXE_LDFLAGS / EXE_LDFLAGS is not provided, then it defaults
to the value of PY_CORE_LDFLAGS which is the existing behaviour.
If both flags are supplied, and there is a need
to distinguish between executable and shared specific LDFLAGS,
in particular, PY_CORE_LDFLAGS should contain the shared specific LDFLAGS.
* documentation for new linker flags
* update Misc folder documentation
* Update Makefile.pre.in

Changing the values requires forking and patching, which is intentional. Simply rebuilding from source does not change the implementation enough to justify changing these values - they would still be `cpython` and compatible with existing `.pyc` files. But people who maintain forks are better served by being able to easily override these values in a place that can be forward-ported reliably.
Along the way, leave a deprecated Tools/wasm/wasi/__main__.py behind for backwards-compatibility.

* Include LDVERSION and EXE in base_interpreter value
In Fedora, build-details.json created and installed for python3.14t
contains "/usr/bin/python3.14" as the base_interpreter value.
Create a correct string, taking into account both LDVERSION and EXE
config variables, similarly to how it's defined in altbininstall in Makefile.

* GH-108819: fix LIBDEST not honoring --with-platlibdir
We look for the pure-Python part of the standard library in
PLATSTDLIBDIR, which may not match the default LIBDIR subdir.
From ``getpath.py``:
```python
...
STDLIB_SUBDIR = f'{platlibdir}/python{VERSION_MAJOR}.{VERSION_MINOR}{ABI_THREAD}'
STDLIB_LANDMARKS = [f'{STDLIB_SUBDIR}/os.py', f'{STDLIB_SUBDIR}/os.pyc']
PLATSTDLIB_LANDMARK = f'{platlibdir}/python{VERSION_MAJOR}.{VERSION_MINOR}{ABI_THREAD}/lib-dynload'
...

While CPython doesn't support `--enable-wasm-dynamic-linking`, external tools like componentize-py do and they have to patch around it. Since the flag is off by default, allowing the flag so external users can add/inject dynamic linking support seems acceptable.
This commit updates CI and configuration from wasi-sdk-25 to wasi-sdk-29
which was released recently. This notably includes stubs for pthreads
which all return errors, so some adjustment in logic is necessary to
retain knowledge that WASI cannot yet spawn threads for example.
This additionally increases the wasm stack allowance to 32MiB from 16MiB
to accomodate the `test_recursive_pickle` test in the
`test_functools.py` file. It looks like the Clang/LLVM update that
happened in wasi-sdk-29 relative to wasi-sdk-25 is likely the cause of
this where presumably functions have more locals than before and/or a
slightly adjusted stack space requirement which overflows the stack.
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).

* Add OpenSSL 3.5.2 definitions to Modules/_ssl_data_35.h (moved from Modules/_ssl_data_34.h)
* Demote OpenSSL 3.1 to "old", remove it from CI
* Update all OpenSSL versions to latest patchlevel in CI config and multissltests defaults
* Add OpenSSL 3.5.2 to CI configuration and multissltests default list
* Fix a typo in the argument parser description of multissltests.py
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.
