Would it be better to add the _CHECK_STACK_SPACE micro-op to the CALL_PY_GENERAL and CALL_BOUND_METHOD_GENERAL macro instructions?

Done.

Actually, those two instructions don't need to check stack space (they use the frame push that can fail, instead of the one that pushes without checks), they only need to check recursion remaining. So I split it into another uop to make things more efficient.

Sorry, @Fidget-Spinner and @markshannon, I could not cleanly backport this to 3.13 due to a conflict.
Please backport using cherry_picker on command line.
