time: Make TimeZoneRule blittable and avoid copies (#3361)

Browse source 
* time: Make TimeZoneRule blittable and avoid copies

This drastically reduce overhead of using TimeZoneRule around the
codebase.

Effect on games is unknown

* Add missing Box type

* Ensure we clean the structure still

This doesn't perform any copies

* Address gdkchan's comments

* Simplify Box
