Upgrade Yarn to v3 (MetaMask#463)

Closes MetaMask#458.

This upgrades Yarn to the latest version, v3, and uses the Yarn v3 workspaces plugin to manage the workspace. The examples package is now a sub-workspace (meaning it can't be published to npm anymore), which removes the need for the build script and solves some issues regarding dependency management as well.
