Hui Xiao 1e0e883ca5 Remove deprecated API AdvancedColumnFamilyOptions::soft_rate_limit/hard_rate_limit (#9452) 
Summary:
**Context/Summary:**
AdvancedColumnFamilyOptions::soft_rate_limit/hard_rate_limit have 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.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9452

Test Plan: Rely on my eyeball and CI
