Cycles: List Level-Zero in oneAPI device requirements in the UI on Linux

Intel documentation for Ubuntu 22.04 does list all runtime components
needed by the driver and oneAPI Cycles device but end-users getting
drivers from (other) sources can easily end-up missing required
Level-Zero Loader and struggle root causing what's wrong in their
system. Calling this requirement out in the UI will hopefull help them.

oneAPI Level-Zero incl. Loader: https://github.com/oneapi-src/level-zero
Common package names: level-zero, level-zero-loader
