WinRT: made all SDL_Windows get sized to the WinRT-defined window size

Browse source 
This change removes some code that attempted to allow non-standard window sizes, the idea of which was to do display scaling, and a hackish one at that.  If display scaling is needed, use SDL_Renderer as appropriate.

/* HACK from DLudwig: The following line of code prevents
SDL_CreateWindow and SDL_UpdateFullscreenMode from trying to resize
the window after the call to WINRT_CreateWindow returns.
This hack should allow a window to be created in virtually any size,
and more importantly, it allows a window's framebuffer, as created and
retrieved via SDL_GetWindowSurface, to be in any size. This can be
utilized by apps centered around software rendering, such as ports
of older apps. The app can have SDL create a framebuffer in any size
it chooses. SDL will scale the framebuffer to the native
screen size on the GPU (via SDL_UpdateWindowSurface).
