[Darwin] Fix availability of exp10 for watchOS, tvOS, xROS. (llvm#98542…

…) (#8981) Update availability information added in 1eb7f05. exp10 is available on iOS >= 7.0 and macOS >= 10.9. On all other platforms, it is available on any version. Also drop the x86 check, as the availability only depends on the OS version, not the target platform. PR: llvm#98542 (cherry-picked from d0d05ae)
