rasterizer_cache: Introduce TextureRuntime and separate CachedSurface
* This commit aims to both continue the rasterizer cache cleanup by separating CachedSurface into a dedicated header and to start weeding out the raw OpenGL code from the cache. * The latter is achieved by abstracting most texture operations in a new class called TextureRuntime. This has many benefits such as making it easier to port the functionality to other graphics APIs and the removal of the need to pass (read/draw) framebuffer handles everywhere. The filterer and reinterpreter get their own sets of FBOs due to this, something that might be a performance win since it reduces the state switching overhead on the runtime FBOs.master
