https://crrev.com/c/3674981 installed CIPD ninja packages.
This CL switches from the old ninja binaries to them.

Note that this CL doesn't change ninja version. the old/CIPD ninja binaries are v1.8.2.

The differences from the old binaries are
- the CIPD packages don't use chromium's clang.
- the CIPD package for Linux doesn't use chromium's sysroot.
- the min macOS version is 10.13, which was 10.6.

On Windows, ninja.exe will be installed under .cipd_bin.
But there are many places that assume that ninja.exe exists on depot_tools root. So this CL also copies the ninja.exe from .cipd_bin to root in cipd_bin_setup.bat.
