LibJS: Use TimeZoneMethods in GetOffsetNanosecondsFor

Browse source 
Update to the latest version of the spec which was refactored to use
time zone methods record. This requires updating a whole bunch of
callers to pass through a record too.

This also ends up improving exceptions on a missing
getOffsetNanosecondsFor method.
