Mojo: Use InterfaceFactory<Interface> for service registration

This adds an InterfaceFactory<Interface> type and allows registering a
service through its provider. Using an InterfaceFactory allows the app
to be in control of the lifetime of the implementation of the interface
and hides all of the implementation details of the interface from the
application library code (i.e. no subclassing impl classes or anything
like that).  The default binding behavior is to bind the lifetime of
the impl to the lifetime of the pipe, but the application
can also weakly bind to a service in cases where it needs to manage
the lifetime explicitly.
