[w3c/manifest] Add optional indication of Service Workers to Manifest (#447)

BACKGROUND: There are some uses cases where apps (often multiple apps) are downloaded/installed/pinned at one time and then not run until a later time.  For example:
• User is browsing a catalog or list of apps and selects multiple web apps to install
• User is restoring a device and all previous apps are installed

If the first run of the web app happens when the user is offline, web app developers who have invested in offline technologies like Service Workers still want the end user to have a good experience. 

PROPOSAL: Enable Web App Manifest authors to (optionally) specify Service Workers that should be instantiated when an app is installed; AND enable these Web App Manifest authors to also indicate if each Service Worker requires individual user credentials

FAQ:
Q: What about Service Workers that require individual user credentials?
A: These Service Workers can be indicated in the manifest so the user agent knows whether or not to instantiate these anonymously
