[w3c/manifest] Manifest-url-only install (Issue #1193)

dmurph created an issue (w3c/manifest#1193)

This has come up over the years, and with the idea of an install element that would need a not-terrible way of fetching app information, I thought we could revisit this.

We can go over why we haven't done this in the past, ways that it might be possible, and other thoughts.


One crazy idea:
- Formalize that an origin can specify a `.well-known/manifest.webmanifest` file. If this exists, then the user agent can find it from an origin.
- Add (back?) the `serviceworker` member to the manifest, to allow user agents to install & activate a serviceworker when install occurs, to allow  the dev to offline any content needed for the site to launch while offline.

Obviously some pros & cons there.
