Use the new features of menu_launch_type in code.
    
    We have enhanced the menu_launch_type to allow for
    start checking and maximizing applications.
    This PR uses the new functions wherever it seems
    logical.
    If special logic was used for certain cases,
    we have not touched these to preserve the
    exact behaviour.
    
    The crash workaround for the Fonts flatpak is dropped because it
    no longer seems to be needed with the latest version of the
    flatpak, and dropping it simplifies this migration.
