fix for test_case_list.xml file w.r.t. nr_dlsim tests. Still a few tests failing, but .xml syntax errors are fixed

Signed-off-by: Raphael Defosseux <raphael.defosseux@eurecom.fr>

- using NR RACH config common from scc
- fixed return type RA preamble target power functions
- retrieving PRACH format from PRACH resources

- takes in input configuration index and TS 38.211 PRACH tables (6.3.3.2.x)
- using FAPI NR UL config request struct, derived from SCF standard for gNB

Now UE gets sync all time in rfsimulator. Yet to be tested with hardware.

modifications for DCI size of format 1_0 for RAR and filling of FAPI for RAR according to special RAR-related configuration

Seems like the UEs in the CI don't like when asked to report NR UE
capabilities. So let's first ask for eutra capabilities and then
dig into them to check for en-dc support and only then ask for
NR capabilities. We chose to ask for NR capabilities after receiving
RRCConnectionReconfigurationComplete. That may not be the best thing
to do.

Today, we do nothing with those capabilities. We could completely skip
asking them to the UE, but since the code is there and since it may be
useful in the future, let's do it. Hopefully, it should not hurt too much.
