Allow creation of EmergencyNumberTracker when CALLING or MESSAGING is enabled

Messaging relies on EmergencyNumberTracker, which is currently tied to
FEATURE_TELEPHONY_CALLING. This prevents messaging from working on
devices with CALLING disabled but DATA and MESSAGING enabled. To resolve
this, EmergencyNumberTracker should be enabled when either
FEATURE_TELEPHONY_CALLING or FEATURE_TELEPHONY_MESSAGING is enabled.
