software/ors-amarisoft: enb.jinja2.cfg: Factor handover code into one place

We currently have LTE-specific handover configuration in under cell_list and
NR-specific handover configuration in under nr_cell_list. Those configuration
are different.

However in upcoming MultiRU we will need to handle LTE->NR handover, NR->LTE
handover, and also Intra-ENB handover in addition to Inter-ENB handover we
currently do.

-> Move handover code into common function as a preparatory step for that.

In the future the handover code for LTE and NR cells will be the same, so it
makes sense to move that code to common place to avoid duplication.

For rendered enb.cfg this unification introduces only space and trivial
changes as shown in the appendix.
