CI: Update the Intel OpenCL CPU runtime

Beginning with SDK 2.18.0, the Windows testing in CI has been unstable.
The test process dies without a Python traceback in a few percent of
runs, usually early in the session.

Analyzing a core dump from CI showed the fault coming from the Intel
OpenCL JIT compiler, which aborts while building the kernels. Our own
frames only call into it, and the same kernel source builds fine in the
runs that pass.

The runtime in use was built in 2023. Attempt to solve this by
upgrading to the current one.
