Move back `new_column_definition` into `TableDefinition`

Only `primary_key` should be extracted by d47357e in #19030, but
`new_coclumn_definition` was also extracted because #17631 is merged
previously, then #19030 is auto merged without conflicts.

This commit is for move back `new_column_definition` into
`TableDefinition`.
