  Message : Add script to apply clang-format on all sources 1. python script wrapper to call clang-format over the whole code base 2. Add clang-format rule `IncludeBlocks: Preserve` to tell clang-format do not merge include blocks 3. Fix existed clang-format issue in code base Bug: angleproject:3532 Change-Id: I289292dc62c2784ff21688065c87c3f3f5538f17 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1709720 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
