4d68c244a7 refactor high-contrast filter
Rewrite as one cacheable runtime effect with uniforms paralleling
SkHighContrastConfig.  This is mostly for style, in the sense of
readability but also how I'd recommend writing these effects generally:
one program body controlled by uniforms.  Callers needing specialization
can write their own effect (or use our TBD uniform->constant facility).

Test isAlphaUnchanged(), and make it so by not saturating c.a.

MaliT880 was producing seriously bad results until I switched to mix().

c0bd9f9fe5 rewrite includes to not need so much -Ifoo
Current strategy: everything from the top

Things to look at first are the manual changes:

   - added tools/rewrite_includes.py
   - removed -Idirectives from BUILD.gn
   - various compile.sh simplifications
   - tweak tools/embed_resources.py
   - update gn/find_headers.py to write paths from the top
   - update gn/gn_to_bp.py SkUserConfig.h layout
     so that #include "include/config/SkUserConfig.h" always
     gets the header we want.

394d414452 Implement SkHighContrastFilter
This is a color filter to apply several contrast adjustments for users
with low vision, including inverting the colors (in either RGB or HSL
space), applying gamma correction, converting to grayscale, and increasing
the contrast.
