LOG: [libc][math] Implement isnanf16 header-only function (#198115)
Adds `isnanf16` the float16 variant of isnan as part of issue
[#195400](https://github.com/llvm/llvm-project/issues/195400), which
tracks adding missing isnan variants for extended floating-point types.
The implementation follows the same pattern as the existing `isnanf`,
`isnan`, and `isnanl` functions.
