Use gtk_widget_set_opacity() with new enough wxGTK3

Browse Source 
This function replaces gtk_window_set_opacity() and could presumably work
better for the GTK+ versions supporting it.

Also avoid deprecation warnings, if they're ever enabled later, for
gtk_window_set_opacity() which we still have to use for older GTK+.

Closes #17106.
