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.

Robert Falkenberg d8cb4ec700 lib,rlc_am_nr: detect gaps in sequence of received SDU segments 
This is required for checks such as
"there is at least one missing byte segment [...] before
the last byte of all received segments of this SDU"

Pedro Alvarez 12f440145d lib,rlc_am_nr: changed build_retx_pdu_without_segmentation to pass retx 
info by copy. This is to avoid accidently using retx info by reference
after pop'ing the retx from the queue.

for each created PDU.

- Remove unused member nack_range from rlc_am_nr_status_pdu_t.
