Add --headless flag to wptrunner

Now that most major browsers have headless mode support, I would
propose to introduce a --headless flag to wptrunner.  This would get
picked up in the different concrete browser implementations which
would do the right incantations to enable headless mode for their
browser.  If the browser does not support headless mode, we can error.

This will make it easier to enable headless mode in a browser you
are unfamiliar with.  For example, if a Chromium developer wants
to run WPT tests in Firefox headlessly they would today first have
to look up what the environment variable name is (MOZ_HEADLESS).
