library/ranap: enrich both t(s|r)_RANAP_DirectTransfer templates
Instead of having two similar variants of RANAP_DirectTransfer:
- t(s|r)_RANAP_DirectTransfer, and
- t(s|r)_RANAP_DirectTransferSAPI,
let's make the first one more flexible, and drop the last one.
This is achieved by introducing two supplementary functions:
- f_gen_ts_dt_ies(), and
- f_gen_tr_dt_ies,
which dynamically compose DirectTransfer.protocolIEs.
