Original change's description:
> Simplify fill path call by removing do_fill_path
> 
> The git diff is not very informative for this CL.
> Here's a better diff:
> 
> 1. do_fill_path is removed and its content is copied to AntiFillPath
> 
> 2. Any call to do_fill_path is removed.
> 
> 3. std::function FillPathFunc is removed (and replaced by direct
>    AAAFillPath, DAAFillPath, and SAAFillPath call).
> 
> 4. The old call chain is:
>      AntiFillPath -> (AAAFillPath/DAAFillPath/...)
>                   -> do_fill_path
>                   -> specific FillPathFunc
>    The new call chain is:
>      AntiFillPath -> AAAFillPath/DAAFillPath/SAAFillPath
> 
> This is made possible by the removal of SK_SUPPORT_LEGACY_AA_CHOICE
> which makes sure that AntiFillPath is the only function that makes
> the choice of AAA/DAA/SAA.
> 
> In the next CL, I'll improve the structure of SkScan::AntiFillPath
> to prepare for Threaded Backend's init-once change.
