[hwasan] Workaround unsupported AssignmentTrackingPass (#76547)

Temporarily fix for issue #76545

Hwasan does not attach tags to @llvm.dbg.assign. It's not clear if we
can attach tags to @llvm.dbg.assign.

For now we just disable the path replacing llvm.dbg.declare with
llvm.dbg.assign.
It may reduce the quality of interactive debugging with HWASAN, but
usually it's
a smaller priority for sanitizers than the quality if reports.
