This fixes a regression caused by MDL-74752. If you regraded
a subsequent quiz attempt in a quiz using the 'Each attempt
builds on last' option, then the student's response could get lost.
Applied the following changes to various testcase classes:
- Namespaced with component[\level2-API]
- Moved to level2-API subdirectory when required.
- Fixed incorrect use statements with leading backslash.
- Remove file phpdoc block
- Remove MOODLE_INTERNAL if not needed.
- Changed code to point to global scope when needed.
- Fix some relative paths and comments here and there.
- All them passing individually.
- Complete runs passing too.
Recently, PHPUnit (all versions) did some changes about how the
comparators worked and this has caused some float comparisons
to stop working.
We need to move them to assertEqualsWithDelta(), allowing a small
tolerance to workaround the floats comparison problem.
0.00001 has been decided. And applied to all the similar assertions
within the unittest function, so if more cases are added to them
better be copied with the agreed tolerance.
This issue greatly improves the performance of displaying statistics in
the question bank.
1. The required quiz statistics are now pre-computed by a scheduled task.
2. Cached statistics in the database are now never cleaned up, so the
pre-computed stats are always available.
3. The way the cached statistics are loaded for each question
that is being displayed is now a bit more efficient.
4. Related to that, there is a new callback which activities can implement,
if they want their question statistics to be included in the ones shown
in the question bank.
Note, there is still further improvement possible to load the statistics
for all questions being displayed in bulk. However, that must wait for a
future issue, MDL-75576. The other improvements in this issue are
significant and we did not want to delay releasing them.

The uniqueidentifier argument is only needed by the version selector and
can be set within the output fragment function using it. There's no need
for it to be a parameter when calling the output fragment function.
