Vedant Kumar 122a6bfb07 [Debugify] Strip added metadata in the -debugify-each pipeline ...

Summary:
Share logic to strip debugify metadata between the IR and MIR level
debugify passes. This makes it simpler to hunt for bugs by diffing IR
with vs. without -debugify-each turned on.

As a drive-by, fix an issue causing CallGraphNodes to become invalid
when a dead llvm.dbg.value prototype is deleted.
