Add visionOS and watchOS to linking to CoreFoundation framework

[simlay]

When using a few patches for various tls and security framework features to build for visionOS and watchOS (among other apple targets), I ran into a linking error.

In rust-lang/rust#125225, linking to Foundation was removed which I think caused some link errors for visionOS and watchOS on rust nightly-2024-05-22.

These are the fixes to those errors.

Yeah, that sounds probable, and this is the correct fix, my apologies that I didn't consider that it might affect badly configured link invocations like this

No worries. It's part of nightly and using tier 3 targets. We'll eventually patch all the links.

@jdm CI failed on rustfmt so I cargo fmt'd, squashed commit and pushed. I think you have to push the "auto merge" button again as I've made a change.

Uh, the auto merge merged the unfmt'd commit? Now CI is red. It ignored my push to fix rustfmt and claims the PR is merged when there's obviously an unmerged commit. I expect better of this free software (github).
