[Temporal] Add PlainDate.prototype.toJSON

Also add AOs: PadISOYear, FormatCalendarAnnotation, TemporalDateToString
Spec Text:
https://tc39.es/proposal-temporal/#sec-temporal.plaindate.prototype.tojson
https://tc39.es/proposal-temporal/#sec-temporal-padisoyear
https://tc39.es/proposal-temporal/#sec-temporal-formatcalendarannotation
https://tc39.es/proposal-temporal/#sec-temporal-temporaldatetostring

Change the ISODateTimeWithinLimits from
-8.64 × 10^21 - 8.64 × 10^16, 8.64 × 10^21 + 8.64 × 10^16
to
-8.64 × 10^21 - 8.64 × 10^13, 8.64 × 10^21 + 8.64 × 10^13
per https://github.com/tc39/proposal-temporal/pull/1723

Change to use AppendCStringLiteral instead of AppendCharacter when
appropriate.
