Summary: X-link: https://github.com/facebook/react-native/pull/41391 Pull Request resolved: https://github.com/facebook/yoga/pull/1461 Converts usages of `YGEdge` within internal APIs to `yoga::Edge` scoped enum. With the exception of YGUnit which is in its own state of transition, this is the last public yoga enum to need to be moved to scoped enum form for usages internal to the Yoga public API. Changelog: [internal] Reviewed By: rshest Differential Revision: D51152779 fbshipit-source-id: 06554f67bfd7709cbc24fdd9a5474e897e9e95d8
