SYCL: Bump oneMath commit (#14152)

Update oneMath commit to merged PR uxlfoundation/oneMath#669
which adds SYCL-Graph support for recording CUDA BLAS commands.

With this change the `MUL_MAT` tests now pass on DPC++ CUDA backends with SYCL-Graph
enabled. Prior to this change, an error would be thrown.

```
$ GGML_SYCL_DISABLE_GRAPH=0 ./bin/test-backend-ops -b SYCL0 -o MUL_MAT -p type_a=f16,type_b=f32,m=16,n=1,k=256,bs=\\[1,1\\],nr=\\[2
