Converts layout.css.devPixelsPerPx to a static pref. This one was one of the slightly odd ones; some values were expecting an atomic float, so instead of defining a regular type float it is defined in StaticPrefList.yaml as an AtomicFloat. I am assuming this was the intent of the pref value all along. Differential Revision: https://phabricator.services.mozilla.com/D42396 --HG-- extra : moz-landing-system : lando
