cherry-pick #17683 to release-4.0
What problem does this PR solve?
Currently, TiDB does not push down expr to TiFlash if new collation is enabled because TiFlash does not support new collation. Now new collation is supported in TiFlash, so we do not need this check anymore.
What is changed and how it works?
What's Changed:
TiDB not check collation status when trying to pushdown expr to TiFlash
