This CL updates the clang format files to have a single shared format between Dawn and Tint. The major changes are tabs are 4 spaces, lines are 100 columns and namespaces are not indented. Bug: dawn:1339 Change-Id: I4208742c95643998d9fd14e77a9cc558071ded39 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/87603 Commit-Queue: Dan Sinclair <dsinclair@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com>
