Enable f16 tests on x86 Apple platforms

tgross35 · tgross35 · commit c3d3d1a12161 · 2024-09-28T19:25:41.000-04:00
These were disabled because Apple uses a special ABI for `f16`. `compiler-builtins` merged a fix for this in [1], which has since propagated to rust-lang/rust. Enable tests since there should be no remaining issues on these platforms. [1]: rust-lang/compiler-builtins#675
