[gtk-doc] Add a flavour for no-xslt builds.



commit cbd9a2f8b93c5c4aa56f089551a1718fbe92998c
Author: Stefan Sauer <ensonic users sf net>
Date:   Tue Oct 16 21:51:24 2018 +0200

    Add a flavour for no-xslt builds.
    
    Using this flavour will use gtkdoc-mkhtml2, which replaces gtkdoc-mkhtml and
    gtkdoc-fixxref. Change mkhtml2 to have the same output dir behaviour like
    mkhtml.
    
    This is autotools only for now. Later changes will add support for the other
    build systems.
