Robert Falkenberg a11291eb08 lib,rlc_am_nr: fix handling of NACK ranges with SO reaching SDU edge 
This changes the handling of NACK ranges with segment offset (SO),
where either so_start or so_end reach the edge of a full SDU.
That SDU is then NACK'ed as a whole, rather than as a segment
from 0 to 0xFFFF.
Otherwise, the search for segments will fail if said SDU was
initially sent as a whole (without segmentation).

Pedro Alvarez c457132570 lib,rlc_am_nr: avoid if that would always be true when checking the

Robert Falkenberg 489259dc78 lib,rlc_am_nr: extend status PDU struct with self-contained packed size info 
This change refactors the rlc_am_nr_status_pdu_t from a simple
container into a class with integrated counter of the packed size.
As this depends on the SN length, the SN length must be passed
via constructor.

- Remove unused member nack_range from rlc_am_nr_status_pdu_t.
