### What problem does this PR solve?
Problem Summary:
Doris's table locks are fair read-write locks. If two threads acquire read
locks on tables in different orders and simultaneously a third thread attempts
to acquire a write lock on one of these tables, a deadlock can form between the
two threads trying to acquire read locks. This PR changes the lock acquisition
order for queries to follow the order of table IDs, ensuring that the lock
acquisition order for tables is consistent among different threads.
### Release note
Execute table locking operations in ascending order of table IDs.
