Add Neon implementation of av1_convolve_2d_sr for 12-tap filter

Add an Arm Neon implementation of av1_convolve_2d_sr for 12-tap
filters and use it instead of falling back to the scalar C function.

The implementation is split into horizontal and vertical helper
functions so that we can more easily provide alternative paths (e.g.
using dot-product instructions) in future patches.
