Add a new variant to the labeling API. This CL will create a new variant which will take both internal name and KHR debug name and send them over to the D3D. This will help us capture KHR debug label better and also prevent for the cases where ANGLE was dropping the KHR labels on the floor when calling the label API right after the commands like glTexStorage2D, glTexImage2D etc. Bug: chromium:1164111 Change-Id: Ifebe8df5435a34692c601c5c35fddc1911bf9d0c Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3192180 Reviewed-by: Rafael Cintron <rafael.cintron@microsoft.com> Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Rafael Cintron <rafael.cintron@microsoft.com>
