[gobject-introspection] Revert "annotationparser: indent _parse_comment_block gtkdoc code"

[Dieter Verfaillie <dieterv src gnome org>]

commit c3f14eeab9ae60a138f85212317f92b737e5ed70

    Revert "annotationparser: indent _parse_comment_block gtkdoc code"
    
    This reverts commit f41525d54f53edd9b0d665397f7c6c755ee3616b and
    adds a more complete solution as the original commit only handled
    empty lines between the GTK-Doc comment block start token "/**" and
    the identifier.
