gh-98724: Fix Py_CLEAR() macro side effects (#99100) (#100070)
The Py_CLEAR(), Py_SETREF() and Py_XSETREF() macros now only evaluate
their arguments once. If an argument has side effects, these side
effects are no longer duplicated.

Use temporary variables to avoid duplicating side effects of macro
arguments. If available, use _Py_TYPEOF() to avoid type punning.
Otherwise, use memcpy() for the assignment to prevent a
miscompilation with strict aliasing caused by type punning.

Add _Py_TYPEOF() macro: __typeof__() on GCC and clang.

Add test_py_clear() and test_py_setref() unit tests to _testcapi.

  This "fixes" compilation issues for the Carbon._OSA module on OSX Leopard
  by purging bindings to OSA's debug API's. Those APIs we're completely
  unsupported on OSX 10.4 and are no longer available on OSX 10.5.

  Note that this patches a generated file. This is somewhat acceptable because
  regenerating the file is non-trivial and wouldn't use system headers anyway.
