Add element reference information to to RTQP tables.
In OLEDB Enterprise, we could find element references by type. Currently, this information is not exposed in RTQP. It would be helpful to be able to identify which type of reference an element is using. One use case is for PI Admin's to generate reports on element hierarchy to ensure the proper reference is being used by builders of the AF DB. This is especially helpful in AF DBs where element references are used to build multiple "views" using the same elements and the reference type could be used in conjunction with the new IsPrimaryPath column for reporting.
