Use early errors in the ISO 8601 grammar to avoid having to create such bizarre productions like TimeHourNotThirtyOneDayMonth, etc. This is an editorial change.

Editorial: Use early errors to simplify time-only grammar
067671d 
Previously the grammar relied on bizarre one-off productions such as
TimeSpecWithOptionalOffsetNotAmbiguous and DateMonthWithThirtyOneDays, to
prevent time strings such as 0119 (01:19 but ambiguous with 19th January)
or 1524-08 (15:24 at -08:00 from UTC, but ambiguous with August of 1524)
from parsing correctly without a time designator.

By using early errors, these confusing productions are no longer necessary
to achieve the desired result.

Closes: #1984
