Use the source root (src/ in Chromium) rather than the checkout root as
the path from which to locate the clang-format binaries.
webrtc uses the Chromium build/tools infrastructure but doesn't have
src/ as a source root path. This change allows us to continue to use
'git cl format' in a standalone webrtc checkout (which would be nice.)
BUG=240309
TESTED='git cl format' works on a trivial test change in both a
Chromium and webrtc checkout.

as part of the Chromium checkout.
This follows the approach used by gn.
Changes include:
- in-the-PATH clang-format trampoline scripts
- clang_format.py, which finds clang-format binaries inside of Chrome
- Hook 'git cl format' to the new binaries and scripts
- Rearrange some code, for reuse between clang_format.py and gn.py
