[Enhancement] Introduction of SYCL backend

[Soujanyajanga]

LBPM currently supports Nvidia and AMD GPUs through CUDA and HIP backends.

We want to contribute a new backend through Intel's oneAPI SYCL. This would enable support for Nvidia, AMD and Intel devices with a single backend. Would you be interested in this feature support?

If so, what would be your recommendations towards supporting this new backend?

Hi team,

We've ported LBPM to SYCL and validated ~60% of the test cases. And, we'd like to discuss regarding raising a PR and aligning with the coding standards.

I will follow up with you via email for a discussion.
