  Log Message:
  -----------
  [MemProf] Extend CallSite information to include potential callees. (#130441)

* Added YAML traits for `CallSiteInfo`
* Updated the `MemProfReader` to pass `Frames` instead of the entire
`CallSiteInfo`
* Updated test cases to use `testing::Field`
* Add YAML sequence traits for CallSiteInfo in MemProfYAML
* Also extend IndexedMemProfRecord
* XFAIL the MemProfYaml round trip test until we update the profile
format

For now we only read and write the additional information from the YAML
format. The YAML round trip test will be enabled when the serialized format is updated.
