[FancyZones] Restore size of zoned windows (#4463)

* Started work

* I can't debug anything, cleaning

* Added settings, [[Not Tested]]

Not even compiled

* Tested, the most basic features work

* Refactor, add RestoreSize

* Added DPI awareness

* Fixed a potential issue with resizing zoned windows

* Fixup: Potentially unsafe memory-layout of std::pair replaced with std::array

* Fixup: Use .data() instead of a pointer

* Further refactoring

* Integrated Win+Arrow keys with the Restore size feature

* Fixed an issue where window's on-screen position is not restored properly

* Fixed a bug pointed out by Enrico
