Add hasIccCard to IccCard and TelephonyManager.

Expose the presence/absence of IccCards in the system.
This is needed to fix bug 2033811 which needs to show
some SIM menus in the Mms app and Contact apps only if
there is a SIM and on CDMA there is no sims yet.

The current implementation assumes CDMA never has an
IccCard this is true at the moment but needs to change.
