Low-impact cleanup of IDisplay (#4818)

Remove unused help-related display code. When NcursesDisplay was
removed[1], help was deprecated. This change removes the remaining
bits and pieces of code.

Remove unused escape-related display code. When NcursesDisplay was
removed[1], escape was deprecated. This change removes the remaining
bits and pieces of code.

Remove uses of unused menu parameters.

Remove unused default_status/default_state argument from checklist.
(This seems safe because not only is it unused, the parameter has
different names in the interface and implementation)
