Subject: AK+LibTimeZone: Add debug only formatter for Optional

I found this handy for debugging, and so might others.

This now also adds a formatter for TimeZone::TimeZone. This is needed
for FormatIfSupported<Optional<TimeZone::TimeZone>> to compile. As
FormatIfSupported sees a formatter for Optional exists, but not that
there's not one for TimeZone::TimeZone.
