Joey Perrott c5c57f6737 build: update to clang 1.4.0 and only run clang format on changed files (#36203)
Update to clang@1.4.0 to gain support for optional changing and nullish
coalescing.  Because this would trigger a change on >1800 files in the
repository, also changes our format enforcement to only be run against
changed files.  This will allow us to incramentally roll out the value
add of the upgraded clang format.
