[fix](storage-engine) _clean_unused_rowset_metas should skip rowsets in _unused_rowsets map (#59390)

### What problem does this PR solve?

`_clean_unused_rowset_metas` could incorrectly remove rowset metas (and
its delete_bitmap) that are still tracked in the `_unused_rowsets` map,
which holds rowsets pending deletion.
The fix adds a check to skip these rowsets during cleanup, preventing
premature removal of `_unused_rowsets`. Otherwise, if query a mow table
with rowsets in `_unused_rowsets` map, and `_clean_unused_rowset_metas`
delete delete_bitmap of these rowset, will get duplicated keys.
