si-interfaces: drop the multi-endpoint interface

It's not well-defined; we'll come back to that later

- * WpSiMultiEndpoint:
- *
- * An interface for session items that provide multiple PipeWire endpoints.
- *
- * This is useful for items that need to expose more than one endpoints while
- * managing the same nodes underneath. For example, an audio playback device
- * may have one input endpoint for sending audio to the device and one output
- * endpoint for monitoring (exposing the adapter's monitor ports).
- *
- * If an item implements both #WpSiMultiEndpoint and #WpSiEndpoint, then the
- * managing session will only inspect the #WpSiMultiEndpoint interface in
- * order to determine which endpoints to export. Effectively this means that
- * such an item should also include itself in the list of endpoints that
- * it exposes through #WpSiMultiEndpoint in order to be exported to PipeWire.
