### What problem does this PR solve?
Issue Number: N/A
Related PR: selectdb/selectdb-core#8342
Problem Summary:
When FileBlocksHolder is destroyed late, the corresponding file block may
already be removed or replaced in block file cache metadata.
`BlockFileCache::remove()` can dereference a stale cache cell during duplicate
cleanup and crash. This PR cherry-picks the fix and its related BE unit tests
from selectdb-core.
