Bruce Dawson b6cb9e0b9a Remove Python 2 support for presubmit Commands ...

PRESUBMIT.py files can invoke other scripts, and those scripts may be
run under Python 2 or Python 3. There are multiple mechanisms that
govern which version will be used, sometimes requiring several flags
to be passed.

This change removes support for Python 2 from this system, thus making
it simpler to invoke Python 3 scripts.

The function parameters that are used to select Python versions are
passed in from multiple places so they still need to be supported, but
they are now ignored. The parameters are deleted to prevent accidental
use.

This change was tested by running this command in a Chromium repo:

  git cl presubmit --force --all
