bitbake: bitbake: cooker,runqueue: send the task dependency tree

Adding a CookerFeature that allows UIs to enable
receving a dependency tree once the task data has been
computed and the runQueue is ready to start.

This will allow the clients to display dependency
data in an efficient manner, and not recompute the runqueue
specifically to get the dependency data.
