[SYCL][E2E] Add -O2 to Matrix/joint_matrix_out_bounds.cpp (#17048)

Computing reference values on host is slow at default `-O0`, making this
test very slow. Before this PR, from CI precommit:

```
Slowest Tests:
--------------------------------------------------------------------------
174.00s: SYCL :: Matrix/joint_matrix_out_bounds.cpp
77.60s: SYCL :: KernelCompiler/kernel_compiler_sycl_jit.cpp
```
