Also convert OSVersion into a proper struct for better type-safety.
Based on in-progress RFC: rust-lang/rfcs#3750. Only implemented for Apple platforms for now, but written in a way that should be easily expandable to include other platforms.

Use
cfg(os_version_min)to avoid weak linkage when we statically know that a symbol is available.Builds upon #136867 (tracking issue #136866), hence why this is still a draft. See the diff in the last commit.
NOTE: This partly exposes implementation details of
cfg(os_version_min)to-Zbuild-std, namely the ability to unconditionally select the newer implementations when passing*_DEPLOYMENT_TARGET. This should only be a performance improvement (or a regression, if we decide to remove the feature in the future).r? rust-lang/libs
