Temporal: Add tests for PlainTime string disambiguation with calendar

This implements the normative change in
https://github.com/tc39/proposal-temporal/pull/2287 which reached
consensus at the July 2022 TC39 meeting.

It adds tests that ensure that PlainTime strings which require a T
designator for disambiguation, are not disambiguated by adding a calendar
annotation.
