Add Neon implementation of aom_convolve8_horiz

Add an Armv8.0 Neon path for aom_convolve8_horiz, and a corresponding
set of unit tests.

A Neon implementation of aom_convolve8_vert will be added in a
subsequent patch.

The Neon code added in this change is mostly a port of the Armv8.0
Neon implementation of the 'vpx_convolve8_horiz_neon' function in
libvpx.[1]
