Add support to drop columns in non V2 tables. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Built the jars in 3.2.0 and dropped columns using alter table: ```sql ALTER TABLE lake.tnt_dp_skeleton_skeletontable DROP COLUMNS (`a`, `b`); ALTER TABLE lake.tnt_dp_skeleton_skeletontable DROP COLUMNS (`a`) ALTER TABLE lake.tnt_dp_skeleton_skeletontable DROP COLUMN `a` ``` We're running Spark 3.2.0 with an external hive metastore; the underlying data is in parquet format in cloud storage. -- This is an automated message from the Apache Git Service.
