[libxml2] Don't index anything in DOC_DISABLE sections

[Nick Wellnhofer <nwellnhof src gnome org>]

commit 92bb889be3bcbd1aaf64286d592f19e2060a273f
Author: Nick Wellnhofer <wellnhofer aevum de>
Date:   Wed Aug 24 00:03:44 2022 +0200

    Don't index anything in DOC_DISABLE sections
    
    Somewhat misleadingly, the DOC_DISABLE directive only disabled warnings.
    Now we really stop the documentation generator from indexing.
    
    This results in additional warnings for xmlThrDef* functions. This should
    be fixed by documenting or deprecating them.
