[gnome-builder/wip/gtk4-port] plugins/buildui: add warning/error status indicator

[Christian Hergert <chergert src gnome org>]

commit a981333e965f2fc03bac9a58b2dfa561babae53c
Author: Christian Hergert <chergert redhat com>

    plugins/buildui: add warning/error status indicator
    
    This is currently placed in a menu button which does nothing, but the next
    step here is to add a popover with various display items. That might allow
    us to remove the info from the omnibar at some point.
    
    More importantly, I want to make the process of "show issues, jump to
    next warning/error" a bit more keyboard friendly w/o moving panels around.
