More changes to the CMakeFiles for better MSVC compatibility. Added in the RelWithDebInfo target and setup copying the Qt 5 Dlls to the output directories.

We don't need to care about XScale or Intel specific ARM stuff.

In CreateExtSaveData, DeleteExtSaveData and CreateSystemSaveData

with a stub for GetSoundVolume

Rephrased some comments.

Removes a TODO.

 in GetTouchState()

Also fixed a bug with CreateExtSaveData that made it unable to create ExtSaveData archives in the SDMC directory.

Pica/VertexShader: Fix a bug caused due to incorrect assumptions of consecutive output register tables.

We now write create a temporary buffer for output registers and copy all of them to the actual output vertex structure after the shader has run. This is technically not necessary, but it's easier to vectorize in the future.

It is used to downscale the input image horizontally and vertically, previously we were only downscaling it vertically so this caused a hard-to-debug memory corruption problem.

Assemblers will exit with an error when trying to assemble instructions with disallowed registers.

This fixes the horizontal lines in Picross E, Cubic Ninja, Cave Story 3D and possibly others
