Add support for sending binary data in websockets

Browse Source 
Summary:This is a reprise of #6327, but with iOS 7.0 compatibility and less `package.json` changes.

**Test Plan:** Load WebSocketExample in UIExplorer app and start websocket test server script (both provided in #6889) and test sending binary data on both iOS and Android
Closes https://github.com/facebook/react-native/pull/6961
