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