Refactor Dashboard JS Shared Components

[mattporritt]

The quiz dashboard and in progress dashboard share several JS components. Currently these are replicated as methods in each dashboard module.
These methods should be refactored out into their own JS modules.

Hi @mattporritt ,

I've created these PRs to solve issue 68. Basically we have now 4 new JS modules that are called from all the dashboards and the student search. For the master branch I had to add a commit to fix unit test because there is a new deprecated function for PHPUnit 10.

Master: #101
Moodle 3.10: #100
Moodle 3.9: #99
Moodle 3.5: #102

(CI test for 35 is failing when try to install Moodle 3.6)

Thank you.
