Yu Zhang 74d419be4d Add support in SstFileReader to get a raw table iterator (#12385) ... Summary: This PR adds support to programmatically iterate a raw table file with an iterator returned by `SstFileReader::NewTableIterator`. For third party tools to use to observe SST files created by RocksDB. The original feature request was from this merge request: https://github.com/facebook/rocksdb/pull/12370 Since keys returned by raw table iterators are internal keys, this PR also adds a struct `ParsedEntryInfo` and util method `ParseEntry` to support user to parse internal key. `GetInternalKeyForSeek`, and `GetInternalKeyForSeekForPrev` to support users to create internal keys for seek operations with this raw table iterator.
