Fix the DispatchCompute error The error happens when a RWTexture is used in shader. However, there is no resource binding to it. We should clear the corresponding UAV in case the previous view type is a bufer not a texture. Meanwhile, this patch removes clearSRVs/clearUAVs since we use unsetConflictingSRVs/unsetConflictingUAVs to do the similar thing.
