Remove tee and output-selector and just link the source pad to the outputs we want as needed. The way we need to prioritize caps negotiation and allocation queries depending on the mode enabled is too custom to be handled using tee and output-selector. This provides more flexibility and doesn't get in the way of proper handling of negotiation and allocation queries.
