Tyler Denniston f548a028ce [svg] Implement gradientUnits="objectBoundingBox"
Currently only works properly when filling rects, since that is the only
node that implements bounds computation with this CL.

Summary of changes:

- Scale gradient coords by object bounds when units are
  kObjectBoundingBox.
- Make fGradientUnits protected instead of private.
- Change default value of fGradientUnits to kObjectBoundingBox, which
  is the default according to the spec.
- Change SkSVGNode::onObjectBoundingBox to take a full render context
  instead of length context.
- Implement bounds computation for SkSVGRect, SkSVGContainer and
  SkSVGUse.
