Introduces a monorepo structure, relies on yarn workspaces to share
dependencies, and lerna for syncing versions across the monorepo.
* Create 2 workspaces:
'packages' and 'website'
* Create 2 public packages:
'babel-plugin-react-native-web' and 'react-native-web'
* Create 1 private package:
'benchmarks'
A simple release script runs the tests, builds the package assets,
increments the package version numbers, git commits and tags, publishes
the package to npm, pushes the changes to github, and releases the
website update.

1. Fix auto-flipping of styles
The StyleRegistry didn't account for LTR/RTL when caching the results of
style resolution. The 'writingDirection' style is no longer flipped; no
clear use case for it.
2. Remove experimental '$noI18n' style prop suffix
This feature is essentially unused, and less likely to be used with the
introduction of 'dir=auto' on 'Text'. Removing also marginally improves
render performance.
