widget: Ignore text direction in gtk_widget_set_state_flags()
widget: Ignore text direction in gtk_widget_set_state_flags()

Previously we did a semi-successful job at ignoring it. Unfortunately
this job was bad enough that we could lose the direction.

We still allow passing in the enum values, because we want code like
this to work:
  set_state_flags (get_state_flags() | SOME_FLAGS)
