[SYCL] List unsupported platforms in sycl-ls verbose mode

[jchlanda]

The runtime is able to recognised banned platforms, this patch provides a way to list them using sycl-ls' verbose switch.

This was suggested a while back, here: #6878 (comment)

Thanks, nothing from my side.

My bad sorry, was a bit too hasty with this one.

@intel/unified-runtime-reviewers would you be so kind and take a look at this, thank you.

[jchlanda]

@intel/llvm-gatekeepers we've got all the approvals now, should be ready to go.

Thank you!

@jchlanda - It looks like this made Plugin/sycl-ls.cpp fail on the HIP machine in post-commit. Could you please have a look?

Yeap, on it.

@jchlanda - Sorry for the post-commit review, but I think we need to reconsider the design of this. This function is now a public interface of a SYCL class, but is not part of neither the standard nor an extension. We either need an extension written for this, or we need it hidden, either in the detail namespace, by making it private or both.

Thank you for the feedback, on it.
