Merge remote-tracking branch 'origin/lte-sim-tools' into integration_2025_w31 (!3530)

remove specific directory for LTE SIM management tools

This is very old code has never been integrated with the "main" OAI
cmake infrastructure and more recent libraries.

This MR integrates the three binaries for LTE virtual sim management in
the regular build process and log system
