 This is an attempt to scaffold yarn workspaces into our repo with as minimal as possible changes to our current setup and directory structure. Essentially this PR moves current `src` into `packages/babel-plugin-react-forget` as a first step to keep everything working. Later on when we're ready we can split out a `react-compiler` package that is decoupled from Babel, but it's too early for that now
