George Steed dff7bad43d [AArch64] Use full Neon vectors in ARGB4444ToARGBRow_NEON 
The existing Neon code narrows the input 16-bit packed data to 8-bit
elements and separates the color channels, causing us to only process
half a Neon vector per instruction for the channel widening from 4-bit
color data to 8-bits.

We can note that the processing being done is identical for all color
channels and therefore we can keep them partially interleaved during the
widening step. This allows us to use full Neon vectors for the whole
loop body.

Reductions in runtimes observed for ARGB4444ToARGBRow_NEON:

 Cortex-A55: -30.7%
Cortex-A510: -44.3%
 Cortex-A76: -51.6%
  Cortex-X2: -54.2%
