a11y: provide a way to ensure clutter accessibility
If gtk_init is called after clutter_init, it can override clutter AtkUtil implementation. In that situation, we can't say that the accessibility is enabled, as the root object would be wrong. In order to provide a way to prevent this: * clutter_get_accessibility_enabled returns true of false depending on the current AtkUtil implemented * cally_accessibility_init always override AtkUtil implementation.
