CI: Harmonize LDPC CUDA and T2 test/analysis in physim

- Introduce "Run_Physim" function for running ldpctest (with CUDA) and
nr_dlsim/nr_ulsim (with T2) in RAN-gNB-N300-Timing-Phytest-LDPC test
pipeline.
- Create "cls_analysis.py" and introduce "analyze_physim" for
log analysis of physim tests.
- Define patterns to be searched in the physim logs.
- Extract and print information about total gNB RX/TX PHY processing time
from nr_ulsim/nr_dlsim logs.
- Remove "cls_physim.py" as it is not used anymore, cleanup "main.py".
