  [RemoveDIs][DebugInfo] Update SROA to handle DPVAssigns (#78475)

SROA needs to update llvm.dbg.assign intrinsics when it migrates debug
info in response to alloca splitting; this patch updates the debug info
migration code to handle DPVAssigns as well, making use of generic code
to avoid duplication as much as possible.
