Summary: This is a complete rewrite of RCTText, the part of React Native which manages Text and TextInput components. Key points: * It's understandable now. It follows a simple architectural pattern, and it's easy to debug and iterate. Text flow layout is a first-class citizen in React Native layout system now, not just a wired special case. It also brings entirely new possibilities such as nested interleaving <Text> and <View> components. * All <Text>-specific APIs were removed from UIManager and co (it's about ~16 public methods which were used exclusively only by <Text>). * It relies on new Yoga measurement/cloning API and on-dirty handler. So, it removes built-in dirty propagation subsystem from RN completely. * It caches string fragments properly and granularly on a per-node basis which makes updating text-containing components more performant. * It does not instantiate UIView for virtual components which reduces memory utilization. * It drastically improves <TextInput> capabilities (e.g. rich text inside single line <TextInput> is now supported).
