WinRT: bug-fix - SDL_SetThreadPriority() didn't work on WinRT 8.x platforms 

WinRT 8.0 (Phone and non-Phone) didn't offer an API to set an already-created
thread's priority.  WinRT 8.1 offered this API, along with several other
Win32 thread functions that were previously unavailable (in WinRT).

This change makes WinRT 8.1+ platforms use SDL's Win32 backend.
