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.
