Imscope updates

- Using imgui docking branch - allows window docking.
- Moved scopes to different windows to allow docking.
- Disabled scatterplot for time domain samples - issues with amount of
  vertices caused segfaults.
- Disabled IQ heatmaps for RX IQ samples on gNB and UE - this was
  incorrect and currently I don't know how to fix it. This will be
  reenabled once it is.
- added a simple menu and disabled demo windows by default.

Merge remote-tracking branch 'origin/nr-ue-threading-improvements' into integration_2024_w48 (!3091)

Update NR UE threading model

This updates the NR UE threading model by preventing calling threadpool
from threadpool and fixes deadlock issues related to processSlotTX. By
making processSlotTX run to completion instead of starting and waiting
for other threads to finish it prevents locking thread pool cores,
therefore prevening deadlocks.

There is a slight difference here compared to the previous version where
I do not use the UL actor as I believe it is not necessary,
processSlotTX satisfies the run-to-completion requirement now. If in the
future any UL procedure would be parallelized using the thread pool it
should either be done in a run-to-completion model or the processSlotTX
function should be taken off the thread pool.

The documentation has been updated.

Added slot and frame to gNbTimeDomainSamples in imscope

NR UL HARQ handling improvements

to avoid printing warning on unexpected HARQ PID for RA

Merge remote-tracking branch 'origin/improve-chanest-single-antenna' into integration_2024_w48 (!3132)

Run the last job of gNB pusch channel estimation inline

In case of 1 antenna this prevents the usage of threadpool which
eliminates the thread pool overhead.  In case of >1 antenna the
threadpool contention should be reduced providing smaller benefits.

NR UE RRC T304 in phy-test mode

RRC timer T304 is stopped upon completion of the associated RA handover
procedure. There is no RA procedure in phy-test mode so T304 should not
be started to avoid unwanted expiration.

NR MSG3 scheduling improvements

- fix wrong condition on MSG3 allocation assertion message
- remove assertion altogether and handle properly the case where MSG3
  can't be allocated

F1AP lib: minor fixes

- add new enc/dec functions
- extend copy function scope
- add compile define
- fix equality check

T2: minor fix for 4x4 processing

- correct max number of LDPC segments for T2 processing
- use pointer arithmetics in retrieve_ldpc_enc_op() in T2 lib to
  optimize loop processing

E1AP Bearer Context Setup encoding/decoding library and unit tests

E1AP encoding/decoding library (TS 38.463) and unit test for:
- E1 Bearer Context Setup Request
- E1 Bearer Context Setup Response

Integrate Tracy with NR UE

This commit enables the optional use of Tracy for profiling NR UE. See
https://github.com/wolfpld/tracy/releases/tag/v0.11.1 for details.

More instructions are in the commit.

to avoid printing warning on unexpected harq pid

Add information about newly added actors to NR UE.

This increases the number of concurrent DL slots processed from 2 to 4.

Add actor library which implements the Actor model (see  https://en.wikipedia.org/wiki/Actor_model).

Implement run-to-completion for processSlotTX. This is achieved by using a new
dynamic_barrier_t which allows to specify callback after the first join has been
made.

This commit introduces dynamic_barrier_t. Its a thread barrier that counts joins
but allows callback to be specified later. See std::barrier for a basic barrier
description.

In case of 1 antenna this prevents the usage of threadpool which eliminates
the thread pool overhead.
In case of >1 antenna the threadpool contention should be reduced providing
smaller benefits.

* this is necessary to enable the PRINT_ERROR logs in the E1/F1 libs

* tac is optional IE, and it was assumed as always present
* is now allocated in DU container by copy_f1ap_served_cell_info
  when present in the updated cell info and missing in the
  DU container

* allocate memory for pointers only if necessary
* removed redundant copies of simple data types

Add and use F1 encode function for Transmission Bandwidth and NR Frequency Info in F1 interface management lib

* simplified number of Cell Group types

* cleanup struct members not compliant to specs 3GPP TS 38.463
* add defines whenever necessary
