[gnome-builder/wip/gtk4-port] plugins/flatpak: add run command provider

[Christian Hergert <chergert src gnome org>]

    plugins/flatpak: add run command provider
    
    There isn't anything using this yet, but the goal is to change all of the
    build system plugins to use this so that we can drop "run" stuff from the
    IdeBuildTarget infrastructure.
    
    Once that is done, we can drop GbpFlatpakBuildTargetProvider too.
