Bug 1581859: Part 4d - Add web progress listeners to WebNavigationContent. r=nika
This ports the WebProgressListener logic from WebNavigationContent.js to the C++ implementation, and adds IPC messages to send them to the parent process. Linkage between the parent IPDL endpoints and the listeners in WebNavigation.jsm is added in a subsequent patch. Differential Revision: https://phabricator.services.mozilla.com/D103215
