MDL-63689 workshop: Add support for removal of multiple context users
The mod_workshop\privacy\provider now implements the new
core_userlist_provider interface. Deleting (erasing) data follows the
same principles as in other existing methods - we do not actually delete
data that might affect other users. Instead, we only erase the sensitive
owned personal information such as provided content.
