MDL-64843 Backup: Course copy user interface

Browse Source 
This patch adds better core support for copying courses.
There is now a simplified and dedicated UI for copying
courses. This can be accessed from the course context
menu or course management screens.

All backups are done asynchronously and there can be multiple
copies of a course in flight at once.
