[offload][lit] Enable/disable tests on Level Zero when using DeviceRTL (#182128)
Since we can now build the DeviceRTL with SPIR-V, redo the
`XFAIL/UNSUPPORTED` specifications for the tests we see passing/failing
on the Level Zero backend with the DeviceRTL being used.

The tests marked `UNSUPPORTED` hang or sporadically fail and those are
tracked in https://github.com/llvm/llvm-project/issues/182119.

This change will allow us to enable CI testing with the DeviceRTL.

Here are the full test results with this change applied, running only
the `spirv64-intel` `check-offload` tests:

```
Total Discovered Tests: 453
  Unsupported      : 206 (45.47%)
  Passed           : 141 (31.13%)
  Expectedly Failed: 106 (23.40%)
```

31% is not a bad start.
