Delete learner's state in staff debug

WIP
- implement the callback clear_student_state
- add a new submission to indicate existing answers are deleted
- add (but commented out) code to partially support revising score
manually.  But full support will require adding logic to persist the
score within xblock
- fix issue with same explanation displayed multiple times in Step 2
