The use case driving this change is a clone mode setup, where the user is hotplugging or unplugging a cloned touchscreen. Even if the output and head are force-enabled, the touch device should still follow the connector connection status. If there is no video signal for the touchscreen (disconnected connector), then the touch input should be ignored as well. When the output is force-enabled, we need to trigger output_heads_changed from connector status changes. If the head or output are not force-enabled, the compositor will likely attach and detach the head as appropriate. In clone mode, the attach or detach needs to trigger output_heads_changed directly. In other cases, it may be handled through the output getting enabled or disabled which are different signals.
