gh-115432: Add critical section variant that handles a NULL object by colesbury · Pull Request #115433 · python/cpython

This adds `Py_BEGIN_CRITICAL_SECTION_OPT` and
`Py_END_CRITICAL_SECTION_OPT`, which accept a possibly NULL object as an
argument. If the argument is NULL, then nothing is locked or unlocked.
Otherwise, they behave like `Py_BEGIN/END_CRITICAL_SECTION`.
