### What problem does this PR solve?
Issue Number: close #65389
Related PR: #xxx
Problem Summary:
After a table stream is created, dropping its base table can leave the
stream with a cached Java reference to the dropped table object.
`information_schema.table_streams` then treats the cached reference as
available and continues to show the dropped base table name.
This PR invalidates a cached base table reference when the cached table has
been marked dropped, so the existing metadata path reports the base table
fields as `N/A`. It also adds a regression case for the live in-memory path:
create base table, create stream, drop the base table with `FORCE`, then query
`information_schema.table_streams`.

Local verification:

could not run in my local environment because `mvn` is not installed.
- Behavior changed:
- [ ] No.
- [x] Yes. `information_schema.table_streams` now reports `N/A` for base
table metadata when the cached base table has been dropped.
- Does this need documentation?
- [x] No.
