py/scheduler: Allow selective handling in mp_handle_pending.

Browse Source 
Extend mp_handle_pending to support three distinct behaviors via
mp_handle_pending_internal():

- MP_HANDLE_PENDING_CALLBACKS_ONLY: process callbacks only
- MP_HANDLE_PENDING_CALLBACKS_AND_EXCEPTIONS: callbacks + raise exceptions
- MP_HANDLE_PENDING_CALLBACKS_AND_CLEAR_EXCEPTIONS: callbacks + clear only

Original mp_handle_pending(bool) preserved as inline wrapper for
backward compatibility.
