Remove the gcc UBSAN builder to use the clang based UBSAN

Details

    • Sprint 6 (24.03.2025), Sprint 7 (07.04.2025), Sprint 8 (21.04.2025)

    Description

      Evidently, that the clang UBSAN is significantly more capable than the gcc based UBSAN.

      There are some significant amount of UBSAN errors that will occur in even the most basic of MTR tests.
