Create Central Version of dataStateToString()

There are currently two slightly-different copies of
dataStateToString().
-TelephonyManager#dataStateToString()
-TelephonyRegistry#dataStateToString()

The TelephonyRegistry version doesn't have a string for the
DISCONNECTING state. In order to have a single copy that can
be accessed from TelephonyRegistry (not mainline) and TelephonyManager
(mainline), move both copies to TelephonyUtils.
