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

This automatically searches the path for a source root (or takes one from the
command line), and then executes the current platform's GN binary inside that
source tree.

This will allow the user to have a "gn" command on their path, and allow our
scripts to run GN without having to bake-in the logic for finding the correct
platform's GN binary.

In Windows (already worked correctly in posix): gclient wouldn't correctly update depot_tools when called.

Refactored away the bootstrap depot_tools update flow which only still existed in Windows.

Set svn:eol-style=CRLF for all .bat files and everything in bootstrap/win/
Set svn:eol-style=LF for everything else.

Also delete depot_tools/git_cl/ since it's not used anymore.
