In the timestamp internal pipeline, the ResolveQuery buffer cannnot be binded as Storage buffer in binding group layout due to it has not Storage usage. Add InternalStorageBuffer for buffer usage and InternalStorageBufferBinding for buffer binding type, make the QueryResolve buffer implicitly get InternalStorageBuffer and only compatible with InternalStorageBufferBinding in BGL, not Storage buffer binding type.
