feat: Make the new courseware MFE the default courseware experience.

- Remove the REDIRECT_TO_COURSEWARE_MICROFRONTEND waffle flag.
- Add a new COURSEWARE_USE_LEGACY_FRONTEND waffle flag that directs
all learners to the legacy courseware experience.
- Skip two failing a11y tests which fail due to the new default of
the courseware MFE.
