SYCL: Add non-contiguous support in ROPE

[qnixsynapse]

Fixed and enabled non-contiguous input support in neox and norm ROPE. Also did a slight formatting.

[Rbiessy]

Did you verify this is tested in test-backend-ops?

[qnixsynapse]

@Rbiessy Yes. Please see: https://github.com/ggml-org/ci/tree/results/llama.cpp/bd/31ff6fac6af10f78ba1bce85670a1ea7def66c/ggml-6-x86-sycl

[Rbiessy]

Right but I mean do the tests have a configuration with non-contiguous rope?
