This is a backport of #30742 for branch-3.1
What changes were proposed in this pull request?
This changes DSv2 refresh table semantics to also recache the target table itself.
Why are the changes needed?
Currently "REFRESH TABLE" in DSv2 only invalidate all caches referencing the table. With #30403 merged which adds support for caching a DSv2 table, we should also recache the target table itself to make the behavior consistent with DSv1.
Does this PR introduce any user-facing change?
Yes, now refreshing table in DSv2 also recache the target table itself.
How was this patch tested?
Added coverage of this new behavior in the existing UT for v2 refresh table command.
