Add WidgetsAndMore bottom sheet

- Contains two rows, one for widgets, and one for "configurable
  shortcuts" that have customization activities
- Extends AbstractFloatingView and uses VerticalPullDetector for
  touch interactions
- No way to show this currently; will add options to popup in followup
