library/GSM_RR_Types: add minimalistic HandoverCommand 

Similar to [1], the existing implementation [2] is unfriendly
to use, so let's work this around by defining a minimalistic
implementation of (RR) Handover Command.

[1] If1a5244a688abed6e6de2bf3f6e19e0e28129ea5
[2] titan.ProtocolModules.MobileL3_v13.4.0
    MobileL3_RRM_Types.PDU_RRM_HandoverCommand_NW_MS
