Start building core_services.mojo.
Instead of having an application for clipboard.mojo, a
view_manager.mojo, et all, we instead will have one core_services
application which provides implementations of all the services compiled
into one physical file so we don't have to pay the cost of //base/ in
each application.
For now, this just moves clipboard.mojo into core_services.
