[clang] [Clang][NFC] Introduce `gpulib` positive flag for `nogpulib` (PR #126567)

[Artem Belevich via cfe-commits]

I agree that we should be able to negate the option (and, perhaps --nocudainc, as well, while we're at that)

That said, perhaps we should reconsider how we implement it.

Originally `-nogpulib` was modeled after `-nostdlib`. So we've got a single-dash option, and no way to undo it.

Now that we do want to undo it, perhaps we should make it a normal double-dash offloading option. and alias `-nogpulib` to the negative variant of it? WDYT?
