[sanitizer] Move __sanitizer_set_death_callback to a more appropriate file

[cryptoad]

Summary

__sanitizer_set_death_callback is a public interface function wrapping
SetUserDieCallback. Said function is defined in sanitizer_termination.cc,
which is not included in all the RT. Moving the interface function to that
file allows to not have a spurious public fuinction in RT that don't use it.
