Merge remote-tracking branch 'origin/SRS-meas' into integration_2025_w24 (!3460)

Browse Source 
SRS configuration

- Fix segmentation fault, a memory leak, and LOGs for SRS usage
  NFAPI_NR_SRS_BEAMMANAGEMENT
- Refactor SRS configuration;
- Add SRS ResourceSet to get the SNR measurements at MAC layer

In this MR we have 2 SRS ResourceSet, for the same SRS Resource. This
way, in addition to obtaining the UL-RI, we also obtain the SNR in the
MAC and fill the PRB Black list.

This branch has been tested with COTS UE and with RFSim. The measured
values seem correct.
