Add cases with multiple draws and dispatches

D3D11 cannot allow the same (sub)-resource bound as both a SRV and an UAV at the same time. If render pipline and compute pipeline access the same texture, must unset conflicting SRVs and UAVs before drawing and dispatching on D3D backend. Currently, these cases could not pass on D3D11 backend.
