[IntelNav] ci: fix Vulkan/ROCm/CUDA package install on jammy runners

First release run exposed three apt-install failures:

* Vulkan: jammy's archive dropped `vulkan-headers`/`glslc`/`shaderc`
  meta-packages. Switch to LunarG's official SDK tarball (same as
  upstream `build-vulkan.yml`) — immune to Ubuntu package renames.
* ROCm: the hosted jammy image ships stale `rocm-cmake 5.0` bits
  that collide with Radeon's 6.x repo. Purge first, pin Radeon's
  repo with apt-preferences priority 600, upgrade to 6.2.4.
* CUDA: Jimver action's `cublas` sub-package resolves to
  `cuda-cublas-12-6` (the CUDA-11 name). CUDA 12 renamed to
  `libcublas-*`. Install directly from NVIDIA's apt repo with the
  real package names.
