The right ancestor class that has the Hierarchy extension applied needs to be used
since it doesn’t have to be the class directly extending from DataObject, which means
the ID and ParentID columns might be in different tables.
* NEW: Add Hierarchy::prepopulate_numchildren_cache()
API: Hierarchy::stageChildren() customisations must be applied to the base class and not include record-specific behaviour.
Adds the ability to prepopulate the cache for Hierarchy::numChildren()
in a batch.
Note that this optimisation means that stageChildren() is not called on
each record in order to calculate numChildren(). This means that the
structure of the stageChildren() query must be the same for all records
and the behaviour cannot be customised only for a subclass of the base
data class. For example, apply your customisations to SiteTree and not
a subclass.
This is an useful part of optimising the query count on tree generation.

* NEW: Add Hierarchy::prepopulateTreeDataCache()
This provides a more extensible way of preopulating caches for optimised
tree generation.
