LibGL+LibGPU+LibSoftGPU: Remove concept of layer in favor of depth

Browse source 
Looking at how Khronos defines layers:

  https://www.khronos.org/opengl/wiki/Array_Texture

We both have 3D textures and layers of 2D textures, which can both be
encoded in our existing `Typed3DBuffer` as depth. Since we support
depth already in the GPU API, remove layer everywhere.

Also pass in `Texture2D::LOG2_MAX_TEXTURE_SIZE` as the maximum number
of mipmap levels, so we do not allocate 999 levels on each Image
instantiation.
