Saved Desks: Implement Type Mapping for crosapi tab groups

This CL implements type mapping for crosapi tab groups.  In order
to do this the app_restore::TabGroupInfo translation unit was
moved to tab_groups.  This is because app_restore has a
dependency on "ash/constants" and crosapi cannot depend on
ash.  This also adds the new target to both the desks_storage
and chrome/browser/ui/ash dependencies and cleans up/changes includes.
