Enforce CALL_PHONE permission for default/system dialer for non emergency calls

This CL fixes a bug where a default/system dialer targeting SDK 23 would
be allowed to place phone calls without the CALL_PHONE permission. This is
because for the default/system dialer, the Telecom system was only enforcing
the CALL_PHONE app_op.

In order to enforce runtime permissions for both SDK 23 and pre SDK 23 apps,
both OP_CALL_PHONE and CALL_PHONE permission must be checked.
