IMPALA-12865: Fix wrong lastRefreshEventId set by firing RELOAD events

When enable_reload_events is true, catalogd fires RELOAD events after
REFRESH finishes reloading the table/partition. The RELOAD event id is
also used to update lastRefreshEventId of the table/partition. This is
problematic when enable_skipping_older_events is true. HMS events
generated after the reload and before the RELOAD event will be skipped.

Solution:
Fetch the current HMS notification event id before the table/partition
is refreshed, and set it as lastRefreshEventId on the metadata object.

Testing:
- Manually verified the issue is addressed.
- Added an end-to-end test which is close to real time issue.
