   MySQL and MariaDB accept 11 compound time units in `EXTRACT(unit FROM expr)` 
and `INTERVAL expr unit` expressions (`SECOND_MICROSECOND`, 
`MINUTE_MICROSECOND`, `MINUTE_SECOND`, `HOUR_MICROSECOND`, `HOUR_SECOND`, 
`HOUR_MINUTE`, `DAY_MICROSECOND`, `DAY_SECOND`, `DAY_MINUTE`, `DAY_HOUR`, 
`YEAR_MONTH`), which previously failed with `Expected: date/time field` or 
`INTERVAL requires a unit after the literal value`:
   
   - https://dev.mysql.com/doc/refman/8.4/en/expressions.html#temporal-intervals
   - 
https://mariadb.com/docs/server/reference/sql-functions/date-time-functions/date-and-time-units
   
   This change adds the 11 compound unit keywords and `DateTimeField` variants 
and recognizes them in `Parser::parse_date_time_field` and 
`Parser::next_token_is_temporal_unit`.
   
   Closes #2693
   
   Dialects: MySQL, MariaDB
