Attachment: Bug 2061477 - Add a View Tab Groups row to the Organize Tabs panel

The panel could suggest and create groups but offered no way to reach the
groups the user already has. Show a "View Tab Groups" row above "Close
Duplicate Tabs" whenever a group exists, open or saved, and open the
tabbrowser's own <tab-groups-list> beside it so selecting one jumps to it.

The row shares the flyout the suggestion previews use, which keeps the two
lists mutually exclusive and reuses the rows, colors, saved-group labels and
context menus that list already owns. Its "New Group" button is hidden here:
creating groups is what the rest of the panel is for.

Closing a window saves the tab groups it had, so the tests now forget saved
groups between cases; without that, groups left behind by an earlier test
decide whether the new row appears.
