Using a git range check for checking progress is wrong when
the last rolled revision and the revision candidate are on
different branches. The range A..B will always show the
commits from the merge-base of A and B until B.
Better compare the tags of the last rolled revision and the
candidate. The candidate's version must be strictly greater
than what's in chromium.

Before this change, out of two versions 4.2.13.1 and
4.2.14, the latter would have been considered the newest.
Now, the timestamp of the commit determines the age, which
allows to roll a patched version first. The auto-roller
will only roll forward (i.e. there needs to be a commit
range between the last roll and the new candidate).
Additionally, this CL does some cleanups:
- Use the sheriff detection mechanism in the auto-roller.
- Require the roll revision parameter in the chromium_roll
script to avoid redundancy. The auto_roll script determines
that revision automatically.
- Simplify the revision summary in the commit message. The
summary will now show last_roll..new_roll, which e.g.
includes the version change CL. It'll now show useful
information for cherry-picks, which it didn't before.
- Remove unused clusterfuzz check. That check is part of the
release process script.

Add a link with instructions about how to assign v8
issues to the chromium roll commit message.
Remove googler mapping feature as it doesn't apply anymore
to any generalist sheriff.

Also create new v8 versions based on the roll ref, which
has some more verification steps than the candidate ref.
Improve bailout regarding existing versions. Only create a
new version if the revisions is in the future.

Moved and renamed the scripts to fit with git.
These changes require documentation updates, updates of
the release spreadsheet and the buildbot side.
