[BLAS] Skip sycl-graph tests on OpenCL and HIP SYCL backends

[EwanC]

As reported in #696 (comment) the sycl-graph blas unit_tests are failing on AMD. Skip these tests until the fails can be investigated functionality can be implemented

CI output from https://github.com/uxlfoundation/oneMath/actions/runs/15996062308/job/45125363025?pr=696

This is failing on an OpenCL CPU backend, my guess is that in 2025.2 Intel OpenCL CPU implementation started supporting cl_khr_command_buffer which is what enables SYCL-Graph on an OpenCL backend. #669 which added these tests didn't take into account the OpenCL path. Enabling this needs further investigation. I've also disabled testing on the HIP backend until the rocm native-command path takes into account graph recording.

@andrewtbarker Looks like like this successfully gets the pre-commit CI green. I think only the OpenCL case is needed to fix CI, but I don't think the HIP backend will work either right now so added that too to be conservative.

I'm not working the rest of the week, but I can look into enabling the tests on those backends in more detail when I'm back.

Thank you for the quick fix!
