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.

GetTexImageOES is used even if not using OpenGL ES to work around a small issue that
happens if using custom textures with texture dumping at the same.
Let's say there's 2 textures that are both 32x32 and one of them gets replaced with a
higher quality 256x256 texture. If the 256x256 texture is displayed first and the
32x32 texture gets uploaded to the same underlying OpenGL texture, the 32x32 texture
will appear in the corner of the 256x256 texture. If texture dumping is enabled and
the 32x32 is undumped, Citra will attempt to dump it. Since the underlying OpenGL
texture is still 256x256, Citra crashes because it thinks the texture is only 32x32.
GetTexImageOES conveniently only dumps the specified region, and works on both
desktop and ES.
