Summary: Provide support for FSBuffer for point lookups It also add support for compaction and scan reads that goes through BlockFetcher when readahead/prefetching is not enabled. Some of the compaction/Scan reads goes through FilePrefetchBuffer and some through BlockFetcher. This PR add support to use underlying file system scratch buffer for reads that go through BlockFetcher as for FilePrefetch reads, design is complicated to support this feature. Design - In order to use underlying FileSystem provided scratch for Reads, it uses MultiRead with 1 request instead of Read API which required API change. Pull Request resolved: https://github.com/facebook/rocksdb/pull/12266 Test Plan: Stress test using underlying file system scratch buffer internally.
