Add cellular cryptography transparency HALs

Adds cellular cryptography transparency HALs:
- IRadioNetwork.setSecurityAlgorithmsUpdatedEnabled enables reporting
  of security algorithm updates from the modem via the new indication
  API IRadioNetworkIndication.securityAlgorithmsUpdated (default
  enabled)
- IRadioNetwork.isSecurityAlgorithmsUpdatedEnabled queries if the
  updates are enabled.
- Indication API: IRadioNetworkIndication.securityAlgorithmsUpdated
- Additionally, we introduce ConnectionEvent, SecurityAlgorithm, and
  SecurityAlgorithmUpdate to encapsulate relevant data from the modem.
