Fixes layout of nodes with YGDisplayNone and YGPositionTypeAbsolute (#1068)

Summary:
Pull Request resolved: https://github.com/facebook/yoga/pull/1068

There is an issue in react-native when the Yoga node position type is set to absolute and display: none is set where the node layout calculation gives the absolute dimensions, rather than the expected 0 x 0.

Here are some OSS issues tracking this:
