[Temporal] Add TimeZone getOffset(Nanoseconds|String)For

Also add the non-intl version of AO
GetIANATimeZoneOffsetNanoseconds which only implement for UTC.
(intl version implement other tz come later)

Also fix bug in JSTemporalTimeZone::offset_nanoseconds() that
"1000000L * offset_milliseconds()" may overflow int32_t before returning as int64_t by first casting offset_milliseconds() to int64_t in the operation so the whole formula is calculating under 64 bits not 32 bits. This bug fix some  *timezone-string-datetime tests.
