Add support for recognizing WPS calls which change caller ID state.

WPS calls can use the *31# or #31# prefixes to enable or disable caller
ID when dialed.  This CL adds support for recognizing calls with these
prefixes as a WPS call.

Test: Added new unit tests to verify dial behavior for WPS calls with
caller ID activate/deactivate prefix.
