…efaultCollation should be consistent with transform ### What changes were proposed in this pull request? This is a followup of #50609 . `fetchDefaultCollation` should be consistent with `transform`, but now `fetchDefaultCollation` tries to get the table metadata from all ALTER TABLE commands, and custom v2 tables may have side effects when returning the table properties. This PR fixes it to only get table metadata for targeting commands that will be handled in `transform`. ### Why are the changes needed? fix potential regressions ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? N/A ### Was this patch authored or co-authored using generative AI tooling? No Closes #50808 from cloud-fan/follow. Lead-authored-by: Wenchen Fan <wenchen@databricks.com> Co-authored-by: Wenchen Fan <cloud0fan@gmail.com> Signed-off-by: Wenchen Fan <wenchen@databricks.com> (cherry picked from commit 4574feb) Signed-off-by: Wenchen Fan <wenchen@databricks.com>
