[DPCPP] Upgrade DPCPP version for CI

[ghost]

I wish to remove the usm tests from the exclude list for
DPCPP and this requires using DPCPP with support for
the sycl::atomic_ref class template. So, the version of
the DPCPP compiler should be upgraded.

LGTM.
FYI, it interferes with #234, which bumps DPC++ version among other things.

@bader Thank you for the information. @psalz could you have a look too?

The current process for updating CI container image versions is somewhat flawed in that the PR itself does not get checked with the new version. If we had merged this PR directly, future CI runs would have failed since with newer versions of DPC++ two additional test categories (exceptions and opencl_interop) fail to compile (while several additional categories do now compile). This is something I tried to address in #234 by introducing versioned image tags, but we ran into some trouble with long compilation times and ComputeCpp.

Anyway, I've opened a new PR #241 that introduces versioned image tags while now also bumping DPC++ to the version you are suggesting here (1f3f9b9), and adding the failing categories to the filter. I'll therefore go ahead and close this PR!
