We'll want to remove the LibGUI dependency from the WebContent process.
This is the first basic step of removing unnecessary LibGUI includes
and swapping out GUI::Painter for Gfx::Painter.
This is a workaround until we can implement a proper <input type=text>
in terms of LibWeb primitives.
This makes google.com not crash in multi-process mode (but there is no
search box.)
