Support NEON anti-aliasing blit function in SKIA
original function has calculation are called repetitively, and
Processed individual pixels only. So Function call overhead was reduced.
And In contrast to the serial data processing in the existing code,
the Neon code processes 8 or 4 pixels in parallel. In contrast to the
serial data processing in the existing code, the Neon code processes
8 or 4 pixels in parallel
