We never hooked up GPUBindGroupLayoutBinding.textureDimension and GPUBindGroupLayoutBinding.textureComponentType to MTLArgumentDescriptor. This is required for all non-2d textures to work.

Should also ensure MTLArgumentDescriptor.access is set to the correct values while we're at it.

we should confirm this is not needed for iPad Pro (12.9-inch) (3rd Generation - 2018)
