IMPALA-14618: Ensure processor clear waits for active event processing
With IMPALA-12709, metastore event processing became multi-threaded.
During metadata reset or invalidate, all DbProcessors and TableProcessors
were cleared without waiting for any event currently being processed
by those processors.
If an event was being processed at the time of clear, it could update
the cache with stale information after the metadata rebuild, leading
to inconsistencies.
This change ensures that processor clear waits for any ongoing event
processing to complete before clearing internal state.
Testing:
- Ran existing tests.
