gh-133296: Publicly expose critical section API that accepts PyMutex (gh-135899)
...
This makes the following APIs public:
* `Py_BEGIN_CRITICAL_SECTION_MUTEX(mutex),`
* `Py_BEGIN_CRITICAL_SECTION2_MUTEX(mutex1, mutex2)`
* `void PyCriticalSection_BeginMutex(PyCriticalSection *c, PyMutex *mutex)`
* `void PyCriticalSection2_BeginMutex(PyCriticalSection2 *c, PyMutex *mutex1, PyMutex *mutex2)`
The macros are identical to the corresponding `Py_BEGIN_CRITICAL_SECTION` and
`Py_BEGIN_CRITICAL_SECTION2` macros (e.g., they include braces), but they
accept a `PyMutex` instead of an object.
The new macros are still paired with the existing END macros
(`Py_END_CRITICAL_SECTION`, `Py_END_CRITICAL_SECTION2`).

Fix: Prevent crash in ctypes.CField when byte_size does not match type size (gh-132470)
When creating a ctypes.CField with an incorrect byte_size (e.g., using `byte_size=2` for `ctypes.c_byte`), the code would previously abort due to the failed assertion `byte_size == info->size`.
This commit replaces the assertion with a proper error handling mechanism that raises a `ValueError` when `byte_size` does not match the expected type size. This prevents the crash and provides a more informative error message to the us
