Use Info Table Provenances to decode cloned stack (#18163)

Emit an Info Table Provenance Entry (IPE) for every stack represeted info table
if -finfo-table-map is turned on.

To decode a cloned stack, lookupIPE() is used. It provides a mapping between
info tables and their source location.

Please see these notes for details:

- [Stacktraces from Info Table Provenance Entries (IPE based stack unwinding)]
- [Mapping Info Tables to Source Positions]
