Xenia for UWP

Initial UWP support for Xenia!

This is an early implementation of UWP running on Xenia!
Make sure xenia-uwp is set to Game mode, otherwise it will crash on launch!

Known problems include:

• Some games crash randomly, related to AMD drivers.
• When a game requires 'OS level input' (aka inputting text, Yes/No prompts, etc), the game may freeze.

Enjoy!
