fix: Fixed broken HiddenContentTransformer when course pacing is self_pace
In case of self paced course we are relying on course end date to determine if a block is visible or not. However, when course blocks API is called with a block_key it breaks since all blocks do not have end field instead only course block has end field. These Changes fetch end date of block from parent or ancestors blocks to make sure we have course end date available while determining block visibility.
We heard about a bug where learners granted extensions would still
lose access to content if it was marked as "hidden after due date".
This was caused by the HiddenContentTransformer using the due date
from collection time (publish time) rather than the user date returned
from the edx-when DateOverrideTransformer.
A small subtletly of this PR is that Transformers with the
FilteringTransformerMixin are executed before those without it so
part of the fix was to make the HiddenContentTransformer not use the
FilteringTransformerMixin to ensure the DateOverrideTransformer had
run first.
