MDL-71576 qbank_viewquestionname: Add View question name to core

This implementation will introduce a qbank plugin "viewquestionname"
which will view the question name 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 name column.
