Use card view settings to show a 'card view' for custom reports in small devices

- new 'set_columns_attributes' method created to add column attributes included in every column cell.
- new 'get_row_cells_html' method created from 'get_row_html', so it can be overriden individually.

- Create a new 'settings' column in reportbuilder_report table and provide an API to manage it
- Add new card view settings to custom reports

- rename 'system_report' template to 'report'
- view.php now uses 'report' template

Merge branch 'MDL-71902-add-site-level-settings-enforcement-for-browsersecurity-settings' of https://github.com/keevan/moodle

This API now accepts an optional parameter 'searchvalue' to search the events

- Applies locked settings to many other quiz general options.
  For example, allows an admin to lock the browsersecurity level so it
  cannot be changed at an instance level, and will apply the 'default'
  option (which is currently None).

- Show a toast notification when saving an audience
- Add form change checker when adding a new audience to prevent user from navigating away if it is not saved
- Remove expand/collapse animation in audience sidebar to be consistent with editor

Not all global search configurations offer the same results as the
default course search does.

The default course search will return courses that the user can see
the details of even if they can see them via a category, even if
they are not enrolled and cannot enrol themselves on it.

The equivalent global search configuration is:

* Global search is enabled
* The course indexing is enabled
* All the name and summary of all courses are included in the results

This patch will only let global search replace the default course
search when those criteria are met.

It will also display on the global search configuration page if global
search will replace the legacy course search.
