[gnome-builder] project-tree: add GbRenameFilePopover

[Christian Hergert <chergert src gnome org>]

commit 2da2bcec8e53aaa31cd23b15d7eaa3035c6f1c7f

    project-tree: add GbRenameFilePopover
    
    It would be nice for this to share more with GbNewFilePopover, but that
    ended up being quite a pain.
    
    This doesn't duplicate all that much, so I'm fine with it for now.
