MDEV-19906 Port show_old_temporals from MySQL 5.6

Browse Source 
Old temporal data types (created with a pre-10.0 version of MariaDB)
are now displayed with a /* mariadb-5.3 */ comment in:

- SHOW CREATE TABLE
- DESCRIBE
- INFORMATION_SCHEMA.COLUMNS.COLUMN_TYPE

For example:

CREATE TABLE `t1` (
  `t0` datetime /* mariadb-5.3 */ DEFAULT NULL,
  `t6` datetime(6) /* mariadb-5.3 */ DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=latin1

Note, new temporal data types are displayed without a format comment.
