runtime/debug: SetCrashOutput sets the FD for fatal panics
This feature makes it possible to record unhandled panics
in any goroutine through a watchdog process (e.g. the same
application forked+exec'd as a child in a special mode)
that can process the panic report, for example by sending
it to a crash-reporting system such as Go telemetry
or Sentry.
Fixes #42888
