Implementing Color32 functions for Neon platforms.

Besides the raw processing improvement provided by Neon, the code uses memory
preteches (pld) which seem to improve performance greatly when dealing with
very large counts.

This was tested using bench where color32 accounts for the majority of the
workload:
bench -match rects_1 -config 8888 -repeat 500 -forceBlend 1
(the forceBlend is there so that the Color32 code does not go through the
special cases where alpha == 0xFF as it would transform color32 into
a sk_memset32.

Numbers averaged over 3 runs:
bench name      | Before | Neon, no pld | Neon with pld | full boost
rrects_1        | 153.9  | 128.3        | 92            | 1.66x
rects_1_stroke_4| 32.8   | 31.4         | 28.45         | 1.15x
rects_1         | 125.35 | 97.2         | 63.59         | 1.97x

Need to apply matrix to advance in generateAdvance (as we already were in generateMetrics)
Fixes b/6833339
Expand existing unittest to detect this (we needed to set both scale and skew on the paint)

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

* Special copy path for small object
* Global Language list instead of constructing a new obj everytime.
