[gobject-introspection/wip/dieterv/drive-by-review: 4/13] tools: use a template to generate the tools scripts

[Dieter Verfaillie <dieterv src gnome org>]

commit 1bc6a34385550a9f83a92a03d66768d308b09644
Author: Dieter Verfaillie <dieterv optionexplicit be>

    tools: use a template to generate the tools scripts
    
    g-ir-annotation-tool, g-ir-doc-tool and g-ir-scanner where identical
    except for the module and function being invoked.
    Avoid code duplication and generate these from a common template.
