Refactored quiz_statistics_table class to remove some duplications by defining and using
format_range(), format_percentage() and format_percentage_range() methods.

Variants should also be treated like random questions in the sense that
a summary row
should be displayed for them as well.
This commit deals with handling variants.
Also the name of the calculated_random_question_summary class has
changed to
calculated_question_summary to be more generic as the summary row is not
specific to random questions only.
Also removed the protected function too_many_subq_and_or_variant_rows
and the const SUBQ_AND_VARIANT_ROW_LIMIT as they were not being used
anymore.

The statistics table have been modified so that the summary row shows the minimum and maximum
values of each column for the set of questions that are being summarised.

Thanks to MDL-49398, we can separate the combined user session and role
definition cache clearing function into two separate functions. At the
same time, we want to identify and remove mark_dirty() calls that were
added for role definition changes but were incorrectly left behind.
Change highlights:
- Remove unnecessary mark_dirty() calls performed after
assign_capability(), unassign_capability(), delete_role(),
deleted contexts, brand new contexts
- Move role definition cache clear from the user-centric
accesslib_clear_all_caches() to the newly created,
role-dedicated accesslib_reset_role_cache()
Without this, we have no coverage of the convert_submissions task. This test
validates it both works normally, and that it also skips queued items that have
exceeded the conversion attempt limit introduced in this improvement.
Without this, its possible to get a document in the editpdf conversion queue
that keeps failing - and in some cases completely crashing the PHP script
despite exception handling - which ends up blocking the processing of the queue
entirely.
This change allows for a configurable number of attempts the conversion
task will perform before removing the item from the queue.
* The columns 'institution', 'department' and 'email' are no longer
automatically included in all quiz result exports.
* These columns can still be used, but have to be configured under
'showuseridentity'.
