The current completion button has specific templates only for the course
view page. However, from now on this component may be used in other
places and it needs a main template to be rendered in a standard way.
In MDL-78744, when the overallcompletion state was added to be displayed
in the activity card, only COMPLETE/INCOMPLETE status were considered.
However, depending on the activity completion settings, there are a
couple of states more that should also be included (COMPLETE_FAIL and
COMPLETE_PASS).
A new method has been added to the cm_completion_details class to
calculate whether a module should be considered or not completed,
based on their completion options and the current value for the
overall complete state.
Deprecate core_course\output\activity_information class and move its code to two
new classes: core_course\output\activity_completion and core_course\output\activity_dates.
In this process refactor activity_completion improving readability and and also deprecate
renderer_base::activity_information() and core_course_renderer::render_activity_information().
