Add "enabled" to SelectPhoneAccountDialogFragment.

This is used to inform the user an account cannot be used right now. On most dual SIM devices, only a single SIM can make calls at the same time. The UI will be implemented in a followup CL.

This CL also packs the parameters of SelectPhoneAccountDialogFragment into a proto. There are too many arguments and it needs structured representation.
