sdong 88875df821 File temperature information should be preserved when restart the DB (#9242)
Summary:
Fix a bug that causes file temperature not preserved after DB is restarted, or options.max_manifest_file_size is hit.
Also, pass temperature information to NewRandomAccessFile() to allow users to hack a solution where they don't preserve tiering information.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9242

Test Plan: Add a unit test that would fail without the fix.
