### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
Queries on `information_schema.table_stream_consumption` always scanned all
streams and partitions, even when predicates such as `DB_NAME`, `STREAM_NAME`,
`STREAM_ID`, or `UNIT` could exclude most of them.
In cloud mode, this also caused unnecessary partition requests to
MetaService.
### What is changed?
- Forward schema-scan predicates from BE to FE for
`table_stream_consumption`.
- Push down `DB_NAME`, `STREAM_NAME`, and `STREAM_ID` predicates before
scanning stream metadata.
- Push down `UNIT` predicates after partition enumeration:
- In cloud mode, only matching partitions are requested from MetaService.
- In non-cloud mode, rows for unmatched partitions are not generated.
