[feature] ui events (#1326)

This PR updates the editor events:
- adds types to the events emitted by the app (by `app.emit`)
- removes a few events emitted by the app (e.g. `move-to-page`,
`change-camera`)
- adds `onEvent` prop to the <TldrawUi> / <Tldraw> components
- call the `onEvent` when actions occur or tools are selected
- does some superficial cleanup on editor app APIs
