ppsspp windows 10 mobile port

[perneky]

I am working on it for a week now. Actually I have it up and running on Windows 10 Universal app for x86. There is some weird scaling issue with the video playback, an issue with the alpha channel in the rendering, need to develop an XAudio based backend for voice, but it works. JIT is tricky in Windows 10 Universal (memory can not be writable and executable at the same time) but totally doable. I can play PataPon and LocoRoco with no problems.

Right now I am able to compile it to ARM, I only need to compile ffmpeg for ARM windows, to make it run on a phone.
