rasterizer_cache: Introduce TextureRuntime and separate CachedSurface

Browse source 
* 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.
