[SYCL][E2E] Remove use of distutils package

[frasercrmck]

This package is deprecated and removed in python 3.12. PEP 632 recommends replacing distutils.spawn.find_executable with shutils.which, which should offer the same functionality.

Also remove another python module which appears unused.

There's a lit-specific lit.util.which that you might find useful since it uses an explicit environment: https://github.com/llvm/llvm-project/blob/main/llvm/utils/lit/lit/util.py#L228

Ah nice thanks, I didn't see that one.

I'm not sure which is preferable, to be honest. I'm happy to take suggestions.

I see there's prior art in migrating to shutil.which (01fdc2a) though admittedly it wraps it to account for .exe files - which I don't think lit.util.which would do either.

Please review this patch. It's stale for a month now.

Sorry for not seeing the previous ping! Feel free to ping more frequently and/or tag specific people, like @ldrumm did.

Looks like a good change. 👍
