Raise AttributeError for non-homogen tables in sycl_usm_array_interface to comply with Python interop expectations
This PR updates the behavior of the sycl_usm_array_interface property for oneDAL table objects to improve compatibility with Python SYCL-aware libraries (e.g. dpctl, dpnp, numba-dpex).
Previously, the property handler used report_problem_to_sua_iface(": only homogen tables are supported");
to signal unsupported table types (e.g., sparse or non-homogen tables). However, this results in a non attribute related error being raised, which breaks compatibility with Python’s hasattr() behavior, and can surface as runtime errors in downstream libraries that probe for SYCL USM compatibility.
The fix aligns with Python data protocol conventions (e.g., array_interface, cuda_array_interface), which require AttributeError to signal absence.
