When building the resource access used when adding dispatch/draw commands to the render graph, the access mask is required. This PR stores the access mask in the shader interface. When binding the resources referenced by the state manager, the resource access info struct is populated with the access flags. In the near future the resource access info will be passed when adding a dispatch/draw node to the render graph to generate the links.
