Includes a manual roll of Dawn, as well as tweaks to the Tint build overrides. Dawn needs git in order to generate a header that has the version of Dawn compiled in. If we use Dawn's GN rules to build it, we need git to generate that file. Our (now updated) Bazel rules to build Dawn do not need to do this because we (Skia) do not use this file [1] [1] https://dawn.googlesource.com/dawn/+/088a600b03679cd20991f145173a573ed9c03480/src/dawn/common/BUILD.gn#177 Change-Id: Id19fdbb9b53fdad2397a0044a4a314b1444faeb0 Cq-Include-Trybots: luci.skia.skia.primary:Build-Debian10-Clang-x86_64-Debug-Dawn,Build-Win-Clang-x86_64-Release-Dawn Reviewed-on: https://skia-review.googlesource.com/c/skia/+/528157 Reviewed-by: Kevin Lubick <kjlubick@google.com> Reviewed-by: Brian Osman <brianosman@google.com> Commit-Queue: Brian Osman <brianosman@google.com>
