Track depth/stencil aspects independently

Browse Source 
This enables depth-stencil textures to track per aspect state
independently. It lifts the restriction that depth and stencil
store ops must be the same as they now have independent clear
states. It will also enable correct barriers on Vulkan and D3D12.
