Remove deprecated RemoteCompaction API (#9570)

Browse Source 
Summary:
Remove deprecated remote compaction APIs
`CompactionService::Start()` and `CompactionService::WaitForComplete()`.
Please use `CompactionService::StartV2()`,
`CompactionService::WaitForCompleteV2()` instead, which provides the
same information plus extra data like priority, db_id, etc.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9570

Test Plan: CI

* Remove deprecated option DBOptions::new_table_reader_for_compaction_inputs.
* Add Transaction::SetReadTimestampForValidation() and Transaction::SetCommitTimestamp(). Default impl returns NotSupported().
* Add support for decimal patterns to ObjectLibrary::PatternEntry
* Remove deprecated remote compaction APIs `CompactionService::Start()` and `CompactionService::WaitForComplete()`. Please use `CompactionService::StartV2()`, `CompactionService::WaitForCompleteV2()` instead, which provides the same information plus extra data like priority, db_id, etc.
### Behavior Changes
* Disallow the combination of DBOptions.use_direct_io_for_flush_and_compaction == true and DBOptions.writable_file_max_buffer_size == 0. This combination can cause WritableFileWriter::Append() to loop forever, and it does not make much sense in direct IO.
* `ReadOptions::total_order_seek` no longer affects `DB::Get()`. The original motivation for this interaction has been obsolete since RocksDB has been able to detect whether the current prefix extractor is compatible with that used to generate table files, probably RocksDB 5.14.0.
