Split mac clang-format sha1 per architecture

In preparation for using clang-format binaries built in clang rolls
which will result in per-arch clang-format executables, use different
sha1 files per architecture.

This updates the main chromium DEPS to use these, but many other
subprojects' DEPS also need to be updated, which will happen in separate
changes.
