[fix](stats) Stats still in cache after user dropped it (#18720)

Browse Source 
1. Evict the dropped stats from cache
2. Remove codes for the partition level stats collection
3. Disable analyze whole database directly
4. Fix the potential death loop in the stats cleaner
5. Sleep thread in each loop when scanning stats table to avoid excessive IO usage by this task.
