Merge remote-tracking branch 'origin/implement_logical_channel_prioritization_ue' into integration_2023_w47

A COTS UE is sending UE capabilities with accessStratumRelease "rel16"
which is not decoded by our RRC. Switching to RRC 16.13.0 lets our RRC
accept these capabilities (and as a positive side effect lets this
particular UE work nicely in NSA fr1).

cleanup means:
- typo: susbend -> suspend
- call nr_pdcp_manager_unlock() where needed
- simplify LOG_XX (remove __FILE__, __LINE__, __FUNCTION__)

note:
nr_pdcp_release_srb() and nr_pdcp_release_drb() don't use
nr_pdcp_release_drb() because they modify the arrays, so
it does not make sense to "abstract" the accesses to
->srb and ->drb.

Security part needs to be checked, may fail to work.
But if it fails, it was probably not working before either.

This commit also contains adding 'static' to nr_pdcp_entity_release()
and nr_pdcp_entity_delete() (it was too complicated to do a separate
commit for this).

We also update stats in free_rx_list() (again, too complicated for
a separate commit).

openair2/RRC/NR/rrc_gNB.c probably needs some more work, it is a
bit ugly to reestablish all the drbs without checking if they
exit. It will generate warnings at runtime. I didn't do it because
I don't know the proper way.
