Apply hairline optimization only if the path renderer wants it
Make the decision to convert thin, non-hairline paths to hairline
paths at the renderer level.
The current nv_path_rendering implementation does not render
hairlines. Rendering the hairlines with normal renderers cause
unneccessary gl program changes, which is quite slow.
Changes the behavior of non-nv_path_rendering paths to always perform
the optimization if the shape ends up being painted by a renderer that
wants the optimization. Previously the optimization was applied only
when callgraph started with SkCanvas::drawPath.
Applies the optimization for GrAAHairLineRenderer and
GrDefaultPathRenderer.
This changes gm results for dashing3_{msaa4,gpu} and drawlooper_msaa4.
