Also fix a few related issues in the pyatomic headers:

Fix _Py_atomic_store_uint_release in pyatomic_msc.h to use __stlr32 on ARM64 instead of a plain volatile store (which is only relaxed on ARM64).
Add missing _Py_atomic_store_uint_release to pyatomic_gcc.h.
Fix pseudo-code comment for _Py_atomic_store_ptr_release in pyatomic.h. (cherry picked from commit1eff27f)
