Rollup merge of #130650 - BlackHoleFox:apple-target-desc-consistency, r=jieyouxu

Fixup Apple target's description strings

Noticed this inconsistency in how the Apple target's had their new descriptions written while looking at https://github.com/rust-lang/rust/pull/130614, and figured it was easy enough to fixup shortly. I think prefixing every OS with `Apple` is clearer, especially for less known ones like `visionOS` and `watchOS`; so that's what was done here along with making the architecture names more consistent and then some other small tweaks.
