Bug Report
Please answer these questions before submitting your issue. Thanks!
1. What did you do?
When tidb_opt_agg_push_down is on, currently it does not support pushing avg function and distinct functions across Join.
After https://github.com/pingcap/tidb/pull/16344, it supports pushing those across Union, we should make it happen w/ Join, too.
2. What did you expect to see?
3. What did you see instead?
4. What version of TiDB are you using? (tidb-server -V or run select tidb_version(); on TiDB)
