re-implement some of the FCVTZS/FCVTMS/FCVTPS/FCVTNS

1

Recent [Qemu confirms](https://github.com/simd-everywhere/simde/issues/1099#issuecomment-2009639035) the different behavior that was seen on [mac M1](https://github.com/simd-everywhere/simde/issues/1099#issuecomment-1792610406) and [a Pixel 4a 5g phone](https://github.com/simd-everywhere/simde/issues/1099#issuecomment-1799379269) versus our previous implementation. To fix this: 1. Revert https://github.com/simd-everywhere/simde/commit/339ffe4ca89bf6698cab0c8420fe813a4e293aec 2. Adjust...

Don't use _Float16 on architectures that do not support it

2

_Float16 is only supported on a few architectures. Let's assume it's not supported unless we know otherwise.
