[RemoveDIs][DebugInfo] Add interface changes for AT analysis (#78460)

This patch adds the preliminary changes for handling DPValues in
AssignmentTrackingAnalysis - very few functional changes are included,
but internal data structures have been changed to operate with DPValues
as well as Instructions, allowing future patches to process DPValues
correctly.
