This adds a simple `compute_context_for_edittree` function that returns the "active" compute context for the given node editor. This is used in various places, but previously one had to construct the compute context in multiple steps (first find the root context (modifier/operator), then handle the tree path). Since the edittree already has a specific active context, there should be an easy way to retrieve that. This also adds a few extra check that avoid redundant work that was done before.
