Add prototype of canCallPhone with no feature ID.

Adding a prototype of canCallPhone which has no feature ID; this is to
fix the fact that a bunch of changes related to feature IDs were not
cherry-picked to AOSP and there is a huge multi-project batch of changes
in AOSP that can't merge as a result.

Test: Manual testing of change.
Test: Re-build cherry-picked code to verify resolution of build issue.
