The IP traffic of a single NRUE works most
of the time in this commit. There seems to
be a bug in the gNB and it will occassionally
crash with a heap-buffer-overflow. This will
be looked at in the next commit.

The changes in this commit include gathering
all of the UCI indications in the queue that
have the same scheduled sfn_slot and sending
them as one aggregated UCI when the scheduled
sfn_slot matches the received ul_tti_request.

When IP traffic is started on the NRUE, the
gNB immediately crashes

MR !1303 : fix bug in GNB MAC nr_store_dlsch_buffer() to handle multipe UEs correctly.

Merge remote-tracking branch 'origin/episys/mel/sa_development_init' into episys/david/nsa_ci_debug_for_sa

Got rid of unnecessary mac->scc check as well

The following was changed in this commit:
 - A new struct in the mac instance was created
   for all emulated L1 fields.
 - NR UE RRC state bug was fixed
 - Checking the RAR rnti based on the MAC instance
   ra.ra_rnti and not hardcoding to 0x10b
 - Modified the name of the new emulate_l2 flag
   to make sense: emulate_l1

The DCIs are filtered already in the NRUE when
the NFAPI messages are handled.

Also, changed some if statement formatting.

In SA mode, we will not be able to process the SIB if
we change for mac->scc_SIB == NULL : return;

So we change the statement for NSA mode

It will likely break SA mode because it will
filter out Msg3. I will come back to this and
fix it for Msg3.

Also, reverted a DCI filtering change to exist again.
