Fix CompositeAfterPaint backface-visibility regression
Previously we set backface visibility to kVisible in the
TransformPaintPropertyNode for any css transform without explicit
backface-visibililty:hidden. This caused CompositeAfterPaint to
unnecessarily create composited layers for descendant transforms
of backface-visibility:hidden, and the composited layers had
incorrect backface visibility (which is crbug.com/1261095).This CL let TransformPaintPropertyNode for transforms without
direct compositing reasons and backface-visibility-hidden inherit
parent backface-visibility to fix the regression.Bug: 1260603
