feat: AMD GPU compute stress via rocm-validation-suite GST (GEMM)

- Add rocm-validation-suite, rocblas, rocrand, hip-runtime-amd,
  hipblaslt, comgr to ISO (~700MB, needed for HIP compute)
- RunAMDStressPack: run RVS GST (SGEMM ~31 TFLOPS/GPU) + bandwidth test
- Add rvs symlink in chroot setup hook
- Pin all new package versions in VERSIONS
