MDL-83527 core_courseformat: refactor course editor action menus
Browse files Browse the repository at this point in the history 
As part of the course format cleanup epic, all course editor action menu
output classes needs to be refactored to be more mantainable and
reusable. Also, it added notes for the final deprecation of many lines
of code in Moodle 6.0.
