Asynchronous NR PHY configuration (#3527)
* Fix a race condition when accessing the NR PHY cfg by the RRC and phy workers.
Rework how the phy cfg is handled, now workers have their own copy that gets updated after a reconfig moving it out of the state class.

* Default initialize sf_len member in sf_worker for consistency.

* Asynchronous NR PHY configuration

* Fix compilation

* Corrected method override and fix unitialised value

* Added carrier equal comparison to avoid aligment byte padding comparison

to current srate isn't needed, and in fact fails for 6 PRBs where both are
indentical always.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.

Andre Puschmann 483a216bd5 ue,stack: refactor handling of radio bearears in UE stack
this is a rather large commit that is hard to split because
it touches quite a few components.

It's a preparation patch for adding NR split bearers in the next
step.

We realized that managing RLC and PDCP bearers for both NR and LTE
in the same entity doesn't work. This is because we use the LCID
as a key for all accesses. With NR dual connectivity however we
can have the same LCID active at the same time for both LTE and NR
carriers.

The patch solves that by creating a dedicated NR instance for RLC/PDCP
in the stack. But then the question arises for UL traffic on, e.g. LCID 4
what PDCP instance the GW should use for pushing SDUs. It doesnt' know
that. And in fact it doesn't need to. It just needs to know EPS
bearer IDs. So the next change was to remove the knowledge of what
LCIDs are from the GW. Make is agnostic and only work on EPS bearer IDs.

The handling and mapping between EPS bearer IDs and LCIDs for LTE
or NR (mainly PDCP for pushing data) is done in the Stack because
it has access to both.

The NAS also has a EPS bearer map but only knows about default and
dedicated bearers. It doesn't know on which logical channels they
are transmitted.
