Remove CallServiceProvider and CallServiceDescriptor do not merge
This CL removes CallServiceProvider. Instead of using a
provider we'll look up ConnectionServices using the package
manager instead.
This CL also removes CallServiceDescriptor. For incoming calls,
connection services will now pass a PhoneAccount instead
of a call descriptor. For outgoing calls we already use
PhoneAccounts for everything.
