Summary: Views and shadow views might want to configure themself once all of their props were set. So far there was no way to do it without writing some synchronization code. This diff adds a `didSetProps` call on both uiviews and shadow views, passing names of all props that were set for convenience. public Reviewed By: nicklockwood Differential Revision: D2699512 fb-gh-sync-id: 65f76e7bcbf5751d5b550261a953c463ed2f4e8a
