MDL-55356 core_search: Change existing search areas to new API

Browse source 
This change considers all existing search areas in Moodle and makes
necessary changes.

Custom change to course search, supported by helper in base.php:

* course/classes/search/mycourse.php

Custom change to message search:

* message/classes/search/message_received.php
* message/classes/search/message_sent.php

Custom change to user search:

* user/classes/search/user.php

Custom changes to module areas, supported by helper in base_mod.php:

* mod/book/classes/search/chapter.php
* mod/data/classes/search/entry.php
* mod/forum/classes/search/post.php
* mod/glossary/classes/search/entry.php
* mod/survey/classes/search/activity.php
* mod/wiki/classes/search/collaborative_page.php

(Note: the unit tests do not exhaustively check every context type
for these, given that's mainly handled by the helper function
which was already tested in the base_activity test.)

Handled by block base class (no change):

* blocks/html/classes/search/content.php

Handled by activity base class (no change):

* mod/assign/classes/search/activity.php
* mod/book/classes/search/activity.php
* mod/chat/classes/search/activity.php
* mod/choice/classes/search/activity.php
* mod/data/classes/search/activity.php
* mod/feedback/classes/search/activity.php
* mod/folder/classes/search/activity.php
* mod/forum/classes/search/activity.php
* mod/glossary/classes/search/activity.php
* mod/imscp/classes/search/activity.php
* mod/label/classes/search/activity.php
* mod/lesson/classes/search/activity.php
