Updated F16 SIGMOID accuracy evaluation stubs for NEON+FP16ARITH
- Add versions using degree-2 polynomial approximations
- Add versions using 1 Newton-Raphson iteration with FMA and RECPS
- Remove versions using single-step range reduction with approximate reciprocal
as even the version with division doesn't attain 5 ULP accuracy
