gsup: add OSMO_GSUP_SUPPORTED_RAT_TYPES_IE and OSMO_GSUP_CURRENT_RAT_TYPE_IE
OSMO_GSUP_SUPPORTED_RAT_TYPES_IE corresponds to the Supported RAT Types Indicator from 3GPP TS 29.002. See 8.1.2 MAP_UPDATE_LOCATION service, which indicates the capabilities of the MSC/VLR to the HLR. So far, have room for eight RAT types in the gsup_msg. That is an arbitrary random choice without any rationale. OSMO_GSUP_CURRENT_RAT_TYPE_IE is useful to communicate the currently used RAN / RAT type of the current subscriber during Location Updating Request.
