MDL-71613 qbank_viewcreator: Add View creator to core

This implementation will introduce a qbank plugin "viewcreator"
which will view the question creator/modifier column in
the question bank view by replacing the core classes. Having
this plugin will give users the flexibility of enabling
or disabling the question creator and modifier column
in the question bank view.
