Support sampling depth and stencil of combined d/s formats

Browse Source 
This CL adds sampling of depth-only and stencil-only texture
views on all backends. However, Metal on macOS <= 10.11 will
need a workaround to use separate depth/stencil textures for
each aspect since it is impossible to sample the stencil
aspect of a combined depth/stencil texture.

Also fixes sampling of depth24plus on D3D12 which had an
incomplete check for determining if a TYPELESS format is
necessary.
