UX spec: https://www.figma.com/design/f6J2lH6XDxLxyzOLr2E8oE/Tab-Grouping-Spec?node-id=22451-17386

In the tab groups list (currently rendered in the List All Tabs menu, but will be rendered in both a new toolbar menu item and the application menu), right-clicking a tab group will open the saved-tab-group-context-menu context menu if the tab group is a saved+closed group or the open-tab-group-context-menu context menu if the tab group is an open group.

In both of these cases, when the context menu opens, we want to list all of the tabs in the group. These context menus should retain their existing options. There should be a divider after the existing options and then the tabs in the group should be listed as menuitems.

The context menu should be scrollable if there are a large number of tabs. We should experiment with this and see if we need to file a new bug to handle large numbers of tabs.

Clicking on a tab in an open group should activate that tab. Clicking on a tab in a saved group should open that tab as a new ungrouped tab in the current window, but leave that tab's data in the saved group (use what was built in bug 2022352).

Right-clicking any of the listed tabs should act like left-clicking -- there is no additional context menu for these tabs.

The context menus are defined in main-popupset.inc.html and the behavior of the context menus are defined in main-popupset.js.
