This will be used to visit all nodes by the visitor for the purpose of
collecting vlaue nodes that should be evaluated.

We need to add another function that returns all potential dependencies
rather than just those that are dependencies given the current state
(blend value). Make room for that by renaming this to a more descriptive
name.

No longer needed as replaced by the more general doBlend() protected
virtual.

This is called by the non virtual performBlend (will be renamed
once old implementation is removed). The key here is that all
nodes in the blend tree will have the exact same layout for the
ClipResults for a given animator. This means we don't need to have
a mapping data structure for every node in the tree. This really
simplifies the blending implementation and will allow us to
parallelise this much better in the future as each blend node
could make use of a parallel_for() or map() type operation.
To achieve this we will need to perform a gather operation that
maps the ClipResults coming straight out of an animation clip
to the ClipResults layout used by the blend tree as described
above. This will be done in a follow up commit.

The resulting duration is independent of which animators the blend
tree is associated with so this can be implemented as a simple set
of virtual functions in the concrete classes.
The value node simply returns the duration of the contained clip; the
additive node returns the duration of the base node; and the lerp node
lerps the durations of the start and end nodes.

This will allow a job to build up a list of clips to be evaluated for
the blend tree. This has enough flexibility to allow us to support
many types of bend node in the future but still allow us to only
evaluate the clips actually needed at any given time and for the
current set of blend node states.

Also rename backend class accordingly.
