Dean Michael Berris 0f84a7d355 [XRay][tools] Support tail-call exits before we write them in the runtime ...

Summary:
This change adds support for explicit tail-exit records to be written by
the XRay runtime. This lets us differentiate the tail exit
records/events in the log, and allows us to treat those exit events
especially in the future. For now we allow printing those out in YAML
(and reading them in).
