graph: add new scheduler

Browse source 
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.
