Discovery: Editing other types of XBlocks

[bradenmacdonald]

We need to investigate how users can edit components in a library that aren't one of the four types supported by frontend-lib-content-components. e.g. how can we let users edit a drag and drop XBlock?

See #1445 which implements edit modals on the unit page. We can probably use a similar approach, adapted for the v2 runtime and using its embed_view as we're already using for XBlock previews.
