LibJS: Add the ToTemporalTime AO and stub the ParseTemporalTimeString AO

Browse source 
This AO is required for a bunch of PlainTime related methods.

As part of this change the `TemporalTime` record was renamed to
`UnregulatedTemporalTime` and a new `TemporalTime` record that matches
the other Temporal parse result records was added. This also has the
added benefit of getting rid of a would be round-trip cast from integer
to double and back in `ParseTemporalTimeString`.
