Optimize 8-tap Neon DotProd path for av1_convolve_y_sr

The 8-tap convolution filters used with av1_convolve_y_sr have all
even coefficient values. Halving these filter coefficients reduces the
intermediate precision requirements inside the convolution kernels,
and allows us to avoid some slower saturating narrow instructions.

Also update some variable naming to be consistent with the rest of the
file.
