UWP rework (#1231)

* First draft of UWP rework.

* Read desc

- Moved UWP specific functions to uwp_events.h
- Removed BaseApp.
- Implemented example UWP lifecycle.

* Added GIF recording and screenshot support.

* Character inputs and filesystem stuff

* Fix game closing on Xbox when B is pressed.

* Fix the gamepad binding hack

* Add as many keys as I believe are possible.

* Implemented mouse locking of a sort.

* Remove rogue todo, the rest are for a game dev using this example.

* Implemented touch how I "think" it should work. I cant test this.

* Review.
