MDL-66326 Global search: Delete from index when courses are deleted
Adds new API support within search engines for optional methods to
delete data for courses and contexts, and implements this for the
two core search plugins (simpledb and solr).
The new API is automatically called when courses or contexts are
deleted. When a whole course is deleted, it only sends the course
delete rather than sending 1,000 separate context deletions as
each activity/block is deleted.
