[SYCL][E2E] Fix two Windows ocloc tests (#14560)

I recently found out ocloc tests weren't running in Windows CI because
the ocloc tool wasn't installed on the runners.

When trying to fix it, I
[hit](https://github.com/intel/llvm/actions/runs/9909706895/job/27379893885?pr=14114)
two failures that would have always failed if we were testing (the other
two are going to be fixed
[here](#14556)).

The first fix disables the test on Windows because it is using `pvc`
which is not available on Windows.

The seconds add a requirement for the OCL CPU driver to be installed
because the test is using `ocloc-aot`, as per the [ocloc-aot
doc](https://github.com/intel/llvm/blob/56e88d591c52a978abdd5e4279853311cae4a55e/opencl/opencl-aot/README.md?plain=1#L11).

The CI testing in this PR is only confirming I didn't break the tests on
non-win ocloc because I haven't enabled Windows ocloc testing yet, but I
manually verified the fix.
