Move GPU emulation from Ryujinx.HLE to Ryujinx.Graphics and misc changes (#402)
* Move GPU LLE emulation from HLE to Graphics
* Graphics: Move Gal/Texture to Texture
* Remove Engines/ directory and namespace
* Use tables for image formats
* Abstract OpCode decoding
* Simplify image table
* Do not leak Read* symbols in TextureReader
* Fixups
* Rename IGalFrameBuffer -> IGalRenderTarget
* Remove MaxBpp hardcoded value
* Change yet again texture data and add G8R8 flipping
* Rename GalFrameBufferFormat to GalSurfaceFormat
* Unident EnsureSetup in ImageHandler
* Add IsCompressed
* Address some feedback
