Fabric: Using LayoutableShadowNode::getTransform in measuring

Browse Source 
Summary: After this change, all measuring operations based on `LayoutableShadowNode::getRelativeLayoutMetrics` will take into account the transformation matrices provided by shadow nodes. This will allow implementing scroll-offset-aware and custom-transform-aware measuring.
