Description
## Enhancement
After https://github.com/pingcap/tidb/pull/47391, We have supported asynchronous merging of global statistics; however, the issue is that this is only a single-threaded merge of global statistics. Therefore, for tables with many columns, this could pose a problem. We need to enhance parallel computation capabilities here to expedite the process.
