Merge remote-tracking branch 'origin/remove_power_reduction_for_MIMO' into integration_2024_w42 (!3004)

This hotfix removes division by num_antenna_ports in PDSCH precoding matrix generation.
These matrices are defined for CSI reporting in this way but here we are using them for
transmission and this results in an unwanted 10*log10(num_antenna_ports) reduction in
transmit power (3dB for 2 antenna ports, 6dB for 4 antenna ports, etc.)

- Update links for the latest Ubuntu 24.04 LTS iso file
- Update docker install to the latest instructions on the official website
- Update UHD to v4.7.0.0 and update dependencies for Ubuntu 24.04

Test configuration: Tested SIB19 reception on SCS120 Khz + 50Mhz bw
config file used:
targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band257.u3.32prb.usrpx410.conf
+ NTN config commands used

    sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band257.u3.32prb.usrpx410.conf --sa --rfsim -d
    sudo ./nr-uesoftmodem --band 261 -C 27533280000 -r 32 --numerology 3 --ssb 72 --sa --rfsim -d --ue-scan-carrier

The Issue is that SIB19 is not being received because of CRC error, only
SIB1 was being received.

Reduce tested DL throughput on Aerial pipeline from 700 to 600Mbps

This changes the way T_IDs are defined. The T_ID macro was using a
integer to pointer cast in order to provide type safety. This trick
disables some compiler optimizations, as explained here:
https://clang.llvm.org/extra/clang-tidy/checks/performance/no-int-to-ptr.html.
Removing the type cast reenables the compiler optimizations.

This MR aims to address warnings raised when compiling for ARM ( tested
with cross compilation, not directly on ARM hardware ).  The addressed
warnings are as follows:

- An unused variable in file oai_dfts_neon.c
- Wrong printf format specifier related to oai_cputime_t
- Wrong parameter type in qam64_qam64 call

This MR closes issue #844

Also, correctly set the pkg-config search path for libraries for the
target system. Also closes: #746

Prior to this commit, the include path for some libraries found through
pkg-config when cross compiling is not correct:

    $ grep include CMakeCache.txt
    blas_INCLUDEDIR:INTERNAL=/usr/include/x86_64-linux-gnu
    ...

This is because we did not tell pkg-config to search in the right path.
Since for cross-compilation, we install packages in parallel in the
system, override the primary directory where the .pc files located, in
the cross-compilation toolchain file for cmake.

Closes: #746

Change call to qam64_qam64 to use (short *) parameters as defined in the function declaration

Since long long is the bigger type ( 8 bytes ) of the two used ( long long and uint32_t ),
and long long is also available on ARM, change this parameter to always have this type.

This allows to always use format specifier '%lld' in the logs that use TICK_TO_US, which would otherwise return long long or uint32_t depending on architecture.

- remove Sphex UE - not used anymore
- remove RAN-L2-Sim-Test-5G from a list of pipelines - currently disabled
- 4G RFSim was moved to cacofonix
- minor cleanup

3GPP 38.331: If absent, the UE applies the SCS as derived from the prach-ConfigurationIndex in RACH-ConfigGeneric (see tables Table 6.3.3.1-1, Table 6.3.3.1-2, Table 6.3.3.2-2 and Table 6.3.3.2-3, TS 38.211 [16]).

This procedure for msg1_SubcarrierSpacing NULL is not implemented, so we aplly the same value of UL SCS.

Introduce CMakePresests.json which is a simple way to perform incremental build using cmake

New configure resets were added:
 - default: Configure compilation with default options
 - tests: Same as above but ENABLE_TESTS and SANITIZE_ADDRESS is ON

New build presets were added:
 - 5gdefault: Build the software for NR rfsimulator test
 - default: same as 5gdefault
 - 4gdefault: Build the software for LTE rfsimulator test
 - tests: build all unit tests

To configure using configuration preset:

`cmake --preset <preset_name>`

To build using a build preset:

`cmake --build --preset <preset_name>`
