Manifest related_applications browser support

related_applications is an array naming platform-specific apps related to the PWA (each entry needs a platform and at least one of url or id); it is the data behind navigator.getInstalledRelatedApps(). prefer_related_applications is a separate boolean hint that asks the browser to favour installing one of those apps over the web app.

The first table covers related_applications and the second covers prefer_related_applications; each member has its own entry in MDN browser-compat-data, so neither table attests to the other member.
