Wenchen Fan 7c586842d7 [SPARK-36380][SQL] Simplify the logical plan names for ALTER TABLE ... COLUMN ... ### What changes were proposed in this pull request? This a followup of the recent work such as https://github.com/apache/spark/pull/33200 For `ALTER TABLE` commands, the logical plans do not have the common `AlterTable` prefix in the name and just use names like `SetTableLocation`. This PR proposes to follow the same naming rule in `ALTER TABE ... COLUMN` commands. This PR also moves these AlterTable commands to a individual file and give them a base trait. ### Why are the changes needed? name simplification ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? existing test Closes #33609 from cloud-fan/dsv2.
