Adds a "tag" system so that entries of dawn.json can be conditionally emitted in different configurations. With a few more dawn.json changes, this will enable generating the exact upstream header. Bug: dawn:1080 Change-Id: I3506dadd485e31786578a3a64c3603c964c5354f Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/62580 Commit-Queue: Kai Ninomiya <kainino@chromium.org> Reviewed-by: Austin Eng <enga@chromium.org>
