This separates the MediaSource storage from the primary BlobImpl storage. The goal here is to separate this simpler process-local storage from the more complex cross-process store. There is very little overlap in how these two types of URLs are used, with a MediaSource URL not being usable anywhere other than in media elements. This makes performing the separation relatively straightforward. The design in this patch attaches the MediaSource storage to the DocGroup, which will limit access to the specific Window Agent. This also makes it simpler to cycle-collect than the previous global-storage based approach. Differential Revision: https://phabricator.services.mozilla.com/D268717
