Reland "Enable the atlas path renderer for GrAAType::kCoverage"

This is a reland of 8cd8e27c2ceb886ec7fb1e91afcd641cf7e7d175

Original change's description:
> Enable the atlas path renderer for GrAAType::kCoverage
>
> This will definitely cause regressions on a whole slew of benchmarks
> that were carelessly regurgitating cached bitmaps until the system
> memory was blown. But the well defined memory limits of the atlas and
> resilience to animation are worth it. If a client still wants this
> type of caching they can always render their own bitmaps using Skia
> and cache them.
