List View: Block selection and edit button

[scruffian]

What problem does this address?

When used in different contexts (like the Navigation list view) it would be useful to disable the "block selection" mechanism in the List View component and instead display and "edit" button which allows users to select the block when they explicitly wish to do so, rather than simply by clicking the block. We already do this in the OffCanvasEditor:

The edit button should open the inspector controls for the block:

We should investigate making this feature part of the List View component itself from with OffCanvasEditor was forked. It's also worth bearing in mind that the edit button might end up being redundant - maybe when block selection is disabled the click simply opens the drill down directly.

I don't think we'll need this now that the OffCanvasEditor doesn't have an edit button.
