Make auto-roll script work with separate Chromium checkouts.

* Add optional --chromium-checkout flag to point out the Chromium checkout to
work in (automatic fallback to current working dir if that's a Chromium checkout).
* Introduce logging and --verbose flag.
* Make functions private and adopt Python style guide.
* Made --dry-run perform the presubmit checks and other stuff for --commit, except the actual commit.
* Add EDITOR=true environment to 'git cl upload' to avoid launching an interactive editor.
* Removed interactive invocation of 'git cl upload' and 'git cl land'
