chore: bump rocksdb to v9.8.4

[aleksraiden]

Bump rocksdb to v9.8.4, a first release in 9.8 release. Full changelog - https://github.com/facebook/rocksdb/releases/tag/v9.8.4

Important to us: addition fixes about leak file descriptions for blobs

Key features

• When Remote Compaction is enabled, do not purge OPTIONS file immediately by DeleteObsoleteOptionsFiles() after SetOptions(). Rely on PurgeObsoleteFiles() to clean up obsolete OPTIONS file after each compaction
• Added a new API Transaction::GetAttributeGroupIterator that can be used to create a multi-column-family attribute group iterator over the specified column families
• All non-block_cache options in BlockBasedTableOptions are now mutable with DB::SetOptions()
• When using iterators with BlobDB, it is now possible to load large values on an on-demand basis, i.e. only if they are actually needed by the application. This can save I/O in use cases where the values associated with certain keys are not needed
• The option allow_unprepared_value is now also supported for multi-column-family iterators
• OPTIONS file to be loaded by remote worker is now preserved so that it does not get purged by the primary host
• Trim readahead_size during scans so data blocks containing keys that are not in the same prefix as the seek key in Seek() are not prefetched when ReadOptions::auto_readahead_size=true (default value) and ReadOptions::prefix_same_as_start = true
• Assigning levels for external files are done in the same way for universal compaction and leveled compaction

Bug fixed

• Fix missing cases of corruption retry during DB open and read API processing
• Fix a bug for replaying WALs for WriteCommitted transaction DB when its user-defined timestamps setting is toggled on/off between DB sessions
• Fix a leak of obsolete blob files left open until DB::Close(). This bug was introduced in version 9.4.0.
• Fix a longstanding race condition in SetOptions for block_based_table_factory options
• Fix under counting of allocated memory in the compressed secondary cache due to looking at the compressed block size rather than the actual memory allocated
• Skip insertion of compressed blocks in the secondary cache if the lowest_used_cache_tier DB option is kVolatileTier
• Fix an issue in level compaction where a small CF with small compaction debt can cause the DB to allow parallel compactions.
• Several DB option settings could be lost through GetOptionsFromString(), possibly elsewhere as well. Affected options, now fixed:background_close_inactive_wals, write_dbid_to_manifest, write_ identity_file, prefix_seek_opt_in_only
