rhi: d3d12: Move the setSR visitor logic and data to the command buffer

Browse Source 
More logical than throwing it in the main rhi backend object.
In addition, holding on to the generated data from the last
setShaderResources() per command buffer has great value if/when
more granular resource updating is introduced at some point.
