[UR] Move adapter tests over to lit

This moves the CUDA/HIP and Level Zero adapter tests over to
lit. New targets are available, `check-unified-runtime-level_zero`,
`check-unified-runtime-hip` and `check-unified-runtime-cuda` where
applicable. The generic `check-unified-runtime-adapter` can be
used to run it all the above.
