[GTK4] Migrate deprecated FontChooser to FontDialog

This moves all native FontChooser bindings from the shared GTK to the
GTK3 component and also defines new GTK4 bindings for the FontDialog
API.

Note: The FontDialog doesn't seem to remember the initial font that is
passed as an argument. This looks like a bug within GTK, given that the
same behavior also happens for the FontDialogButton[1].
