The idea is to eventually consolidate all runners into one. This PR is just another piece of the puzzle.

Once we're all happy with how the runners work, we should common them up using command line options to select the "type" and CMake options to enable particular runner types (depending on the runtimes and hardware available).

Agreed! The SYCL runtime here is just being used to abstract the LevelZero calls, but this work will be helpful when adding a full SYCL runner (actual language extensions and libraries) to other CPUs/GPUs later.
