library/GSUP_Types.ttcn: add CHECK-IMEI message
Implement necessary messages for Procedure Check_IMEI_VLR (TS 23.018
Chapter 7.1.2.9). This lets the VLR ask the EIR to check if an IMEI
is valid. In the Osmocom stack, we don't have an EIR and this request
is handled by the HLR. We are able to store the IMEI in the HLR as
side-effect (OS#2541).
This is roughly based on TS 29.002 8.7.1 MAP_CHECK_IMEI service, but
only implements the bare minimum required IEs (imei and imei_result).
Related: OS#3733
