Remove "Build Links" field and related code from Projects content type
Based on the discussion that took place on the following issue: https://gitlab.eclipse.org/eclipsefdn/infrazilla/-/issues/2685#note_6938324, we need to remove the Build Links field and all associated code because this is no longer needed.
* Remove the field from the Projects content type
* Delete all related code, including:
* Field formatter code
* Any other references to the field
