Delete small pieces of dead code

- allows for simplification of the log collection in SA-2x2 pipeline
- ci-scripts/Jenkinsfile-nrue can be reused
- to be tested!

- Note: "version" parameter reported as obsolete by docker version > 25.0.5

 - Enable build of T2 lib in RAN-gNB-N300-Timing-Phytest-LDPC
 - Add testcases with 2 layers

Add ulsch decoding measurements, which are reported by nr_ulsim. Start ulsch_decoding_stats measurement before
nr_ulsch_decoding is called and stop it after collection of all decoder tasks from Tpool. In the context of nr_ulsim,
ULSCH_id is allways == 0, testing is performed per one TB, therefore measurement is started and stopped only once per trial.
Reported ulsch decoding statistics show the mean ulsch decoding time over x trials (specified by -n command line option of nr_ulsim).
This measurement does not provide valid information in case of nr-softmodem, when the loop is done over multiple ULSCH IDs -
start of the measurement is done multiple times and stops only once in this case.
For unitary physical simulators, ULSCH processing loop is executed only once
- the max number of PUSCH is set to 1. This ensures exactly one start and stop
of the ULSCH decoding time measurement per processed TB.

Note: ulsch decoding statistics reports average time of segmentation, rate matching, interleaving and decoding of the TB

- Enable both nr_ulsim and nr_dlsim test with Run_T2Test
- Introduce time threshold variable for T2/CPU LDPC tests
  - Set threshold individually for each test - T2 encoding/decoding and CPU encoding/decoding
  - Check if encoder/decoder processing time is below the threshold
  - Remove NOK return option - keep only OK (processing time below threshold) or KO (proceesing time beyond threshold)
- Rename function to run and check results of CUDA ldpctest
- Use new SSH class in function for check T2 test results, use f-strings

- Modify T2 PCI adr for CI T2 test setup
- Set PKG_CONFIG_PATH env var manually if needed (DPDK lib installed into custom path)
