This creates a new BackupService component that lives under browser/components/backup. It doesn't do much yet, except allow itself to be instantiated (which currently occurs using the idle scheduler in BrowserGlue) - but it does set us up to have docs, SphinxJS exporting for JSDoc, linting, etc. Differential Revision: https://phabricator.services.mozilla.com/D202753
