Make operations/metrics settings extensible

Step 3 - Decouple resizeable_panel from collapsible_sidebar

See merge request gitlab-org/gitlab!32462

- Adds resizable flag to resizable_panel to control the
  ability to resize or not. This is helpful when resizable is
  wrapping both the nav and the viewport. When the
  viewport is closed, we don't want to resize anything
- Removes unnecessary div in collapsible_sidebar
- Removes some unnecessary CSS setting width
  since this is managed by resizable_panel
