Per-Partition support for "alter table xxx compact tiflash replica"

## Enhancement
In https://github.com/pingcap/tidb/pull/34741, `ALTER TABLE [name] COMPACT TIFLASH REPLICA` syntax has been added. Deal with partition tables, allowing more fine-grained control. The syntax can be extended as: `ALTER TABLE [name] COMPACT PARTITION [PartitionNameList] TIFLASH REPLICA`
