Clear11 VerticesTransform, RasterizerStates, ScissorRect

- Skip clears if an empty scissor rect is set - Use rastStates to apply scissoring instead of recomputing the scissored positions and updating the VB and updating the VB for every clear - Use ComPtrs for VB and RasterizerStates BUG=angleproject:1934 Change-Id: Ib4448d8568b465df5de57607be4985095f6bd014 Reviewed-on: https://chromium-review.googlesource.com/453881 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
