Optimize deswizzling implementation and support multiple formats

Browse Source 
The deswizzling implementation currently writes linearly and reads non-linearly, this is non optimal as the MMU cannot read ahead. This flips that and reads linearly while it writes non-linearly. This is based on: 324a3624ac/nx/source/display/framebuffer.c (L189).
