Gitlab CI: enable test for the sycl CPU backend

[SimeonEhrig]

I didn't expect, that it will work now, but it is interesting.

Good! The tests that fail are due to the OpenCL CPU runtime :(

Do you know the problem? At the moment, I'm not sure if this a bug in alpaka or a problem of the driver of the CI runner. I would need to reproduce it locally to find it out.

Something is broken in the runtime. I do not think is a bug in alpaka because all the tests pass with an older runtime (see #2140).

I see. So ether we wait until Intel fixed the problem or we add an older additional OneAPI runtime version for runtime tests. Or is there any feature missing, which disallow this?

As I wrote in the README, the only problem is that there is a bug in all_of_group/any_of_group methods (that does not affect the results of the tests). For that we have a workaround, for the PI_ERROR_OUT_OF_RESOURCES no and wait for Intel to fix it means potentially wait a lot.. I would go with adding an older runtime version for the tests
