George Steed 1c31461771 [AArch64] Add Neon dot-product implementation for ARGBGrayRow 
We can use dot product instructions to apply the coefficients without
needing to use LD4 deinterleaving load instructions, and then TBL to mix
in the original alpha component. This is significantly faster on some
micro-architectures where LD4 instructions are known to be slow compared
to normal loads.

Reduction in cycle counts observed compared to existing Neon code:

 Cortex-A55: -12.6%
Cortex-A510: -48.6%
 Cortex-A76: -39.7%
Cortex-A720: -52.3%
  Cortex-X1: -63.5%
  Cortex-X2: -67.0%
