[gnome-builder/wip/gtk4-port] plugins/web-browser: add simple web browser plugin



commit 1c2d8152cf6eb756496adbdaccf3d6158609860a
Author: Christian Hergert <chergert redhat com>

    plugins/web-browser: add simple web browser plugin
    
    This is part of the work to start splitting up functionality from various
    aspects of the html-preview plugin. We want it split into various plugins
    rather than one which gets a bit hard to track what's going on.
    
    This just adds a very simple way to create a new IdeWebkitPage separate
    from all of the preview functionality. Primarily to test the widget before
    porting the rest over.
