GPU: Refactor gpu_texture_image to not use GL calls

This is also a bit of code cleanup, reorganisation.

Tried to be DRYed but avoid too much code change to (hopefully) minimize
breakage.

- GPU: remove TEXTARGET_CUBE_MAP, this is no longer used in the codebase.
- GPUTexture: Move compressed texture upload to gpu_texture.cc
- GPUTexture: Add per texture Anisotropic filtering switch
