Revert "keep SVG arcs axis aligned"

This reverts commit c3823848483eba33c3fa36187de7713e87651c1c.

Reason for revert: need to add legacy flag to chrome first

Original change's description:
> keep SVG arcs axis aligned
> 
> Computing the arc width introduces rounding errors that cause the
> arc to exceed 1/4 circle and cause integer anchored arcs to start
> outside their marks. A round rect may lose convexity as a result.
> 
> Check if arcTo() inputs are integers and arc is 90 degrees;
> if so, output conics which are axis-aligned on integers as well.
> 
> This is triggered when using SVG to represent a round rect.
> 
> Possible future enhancements are recorded in bug.skia.org/7383
