Add EnzymeCore extension for parent_job

[vchuravy]

Alternative to #2260, depends on EnzymeAD/Enzyme.jl#1328

[maleadt]

LGTM!

Marking as draft since the dependent PR hasn't been merged yet (to save on CI resources).

[vchuravy]

Okay this should be ready now.

[maleadt]

Looks like NNlib will need an EnzymeCore compat bump for CI to pass here (normally we detect installation issues of downstream packages and soft-fail that job, but here EnzymeCore is only a test dep so the failure happens during Pkg.test).

[wsmoses]

here's the NNlib bump: FluxML/NNlib.jl#571

This works for JuliaGPU/KernelAbstractions.jl#454 . Can we merge this?

[vchuravy]

We need Enzyme.jl v0.12 to be released. Otherwise we make Enzyme and CUDA uninstallable together.

[michel2323]

Enzyme v0.12 is released Let me know if there's something I can do.

[wsmoses]

@vchuravy these test failures seem unrelated. good to go?

[maleadt]

Yeah, the sorting failure is #2331. I've restarted the job.
