IMPALA-7973: Add support for fine grained events processing for
partition level HMS events.

This patch adds support for fine grained updates for add/drop/alter
partition events.

Currently, partition events invalidate the table. This can be
expensive for large tables. Here, we refresh affected partitions
in case of add/drop/alter partition events. HMS processes add/drop
partitions in a transaction, which means there may be multiple
partitions affected in a single add/drop event. We try to refresh all
these partitions in a loop. If any of the partition refresh fails,
we throw MetastoreNotificationNeedsInvalidateException to mandate a
manual invalidate for event processing to continue.

Testing:
Modified pre-existing tests for partition events to instead test if
partitions are added/dropped/altered when event processing is enabled.
