Refactor GuestOS protocol handler interface.

First step towards implementing
go/borealis-installer-entry-point#heading=h.gjmxdv9g632b.

* Abstracts "app registrations" from "URL handlers". In this model,
  a "URL handler" is just a name and a callback, so can be constructed
  without necessarily needing a Registration. This will be needed in
  the next step.

* Most logic moves into GuestOsRegistryService as a side-effect.
  Since it houses the app list, it also becomes responsible for checking
  which apps support which protocols, and creating the handler callback.
  This change is not strictly necessary, but it feels more natural,
  and gives us a place to register non-app URL handlers in the next CL.
