Add CAPABILITY_ALLOWED_NETWORK_TYPES_USED

* Made the HAL version available to radio interface capabilities
* With version 1.6 of the Radio HAL, a new function was added to enforce
the user network types preference (setAllowedNetworkTypeBitmap).
Depending on the version implemented by the modem the
setPreferredNetworkType and setAllowedNetworkTypes TelephonyManager API
methods may use this new HAL method or rely on the previous method
(setPreferredNetworkType). This new capability enum value can be used by
TelephonyManager consumers to know which HAL function is effectively
backing up their calls.
