Additional Sigmoid micro-kernels and accuracy evaluation stub

- PSIMD micro-kernels and accuracy evaluation stubs
- ARM NEON micro-kernels using 2048-entry table lookups
- ARM NEON micro-kernels with alternative division implementations
- ARM NEON micro-kernels without FMA
- x4..x24 version of all SIMD micro-kernels
- Eliminated comparison with one_cutoff & corresponding blend in all
  micro-kernels
