Considers a block complete only if all scored & graded leaf blocks are complete.

readings or videos) do not count. We only care about actual homework content.
Compare with is_block_structure_complete_for_assignments in course_experience/utils.py, which does the same
calculation, but for a BlockStructure node and its children.
Returns:
True if complete
False if not
