Add changes to use work_item in epic
What does this MR do and why?
I have added the WorkItemGroupQueryBuilder class and kept it behind search_epics_uses_work_items_index to power epics search using work_items index.
I plan to add changes related to aggregations in a follow-up MR and enable the ff once both the MRs are merged.

How to set up and validate locally
Numbered steps to set up and validate the change are strongly suggested.
- Make sure you have advanced search enabled.
- Enable the ff
search_epics_uses_work_items_index - Then do a epics search and notice in the query from performance bar you have the search going to work_items index instead of the issues index in elasticsearch.
- Test the scenarios with and without ff for global and group search.
