Remove deprecated API AdvancedColumnFamilyOptions::rate_limit_delay_max_milliseconds (#9455)

Summary:
**Context/Summary:**
AdvancedColumnFamilyOptions::rate_limit_delay_max_milliseconds has been marked as deprecated and it's time to actually remove the code.
- Keep `soft_rate_limit`/`hard_rate_limit` in `cf_mutable_options_type_info` to prevent throwing `InvalidArgument` in `GetColumnFamilyOptionsFromMap` when reading an option file still with these options (e.g, old option file generated from RocksDB before the deprecation)
- Keep `soft_rate_limit`/`hard_rate_limit` in under `OptionsOldApiTest.GetOptionsFromMapTest` to test the case mentioned above.

 * Remove deprecated option DBOptions::skip_log_error_on_recovery.
 * Remove ReadOptions::iter_start_seqnum which has been deprecated.
 * Remove DBOptions::preserved_deletes and DB::SetPreserveDeletesSequenceNumber().
+* Remove deprecated API AdvancedColumnFamilyOptions::rate_limit_delay_max_milliseconds.
 
 ### 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.
