perf annotate-data: Add pr_debug_scope()

The pr_debug_scope() is to print more information about the scope DIE
during the instruction tracking so that it can help finding relevant
debug info and the source code like inlined functions more easily.

  $ perf --debug type-profile annotate --data-type
  ...
