graph: add new scheduler
Move the activation state to the graph Replace an old scheduler with a new one that works with the new activation states. Remove the DISABLED port flags, we explicitly add and remove to make ports enabled/disabled. Find first compatible port for link Remove the node based scheduler and use the spa one.
