Add context menu submenu to add tab to existing tab group.

Reuses (and slightly simplifies) some of the logic used to add tabs to
new tab groups.

This CL is part of the prototype of the above-described tab groups
feature.  The prototype will allow users to create and manipulate groups
primarily via tab context menus, and will display tab group affiliation
in the tabstrip.  Future work will include persisting and syncing groups,
manipulating groups via tab dragging, and a dropdown menu for the group
headers. See go/chrome-tab-groups-design
