gtk4: Set grayscale antialias again

GPU-accelerated GSK renderers don't support RGB / subpixel antialiasing,
so it doesn't make much sense to use Cairo fonts with subpixel antialias.
That helped with GDI fonts because grayscale rendering of Cairo GDI fonts
looks pretty bad. Now that Pango uses Cairo DWrite fonts we can drop the
patch.
