fix(esp_event): Handler unregistration by itself issue

Browse Source 
when esp_event_handler_unregister_with_internal cannot take
the loop mutex (e.g., when the handler unregisters itself),
create an event with a special base identifier and add it to
the queue of the corresponding loop to postpone the removal
of the handler from the list at a time when the loop mutex can be
successfully taken.
