URL: https://github.com/apache/doris/pull/53383
### What problem does this PR solve?
**Background:**
The MTMVRelationManager maintains a mapping relationship between base tables
and materialized views (MTMVs).
When an MTMV is dropped, this relationship is maintained by removing the
relevant mappings.
When an MTMV is successfully refreshed, the mapping is updated (old mappings
are removed and new ones are added).
**Suspected Issue Scenario:**
The MTMV is refreshed successfully.
The MTMV is dropped.
The mapping relationship is refreshed (potentially causing inconsistent
state).
