resample: add neon optimised code if supported on target

- Add NEON optimized inner_product_single for fixed point.
Semantics of inner_product_single have also been changed to
contain the final right shift and saturation. This change
affects fixed point calculations only.

- Force full sinc table (e.g. no polynomial interpolation)
