[KLIB Resolver] Deprecate Logger.fatal()

Invocation of Logger.fatal() may cause severe side effects such as
throwing an exception or even terminating the current JVM process
(check various implementations of this function for details).

The code that uses Logger.fatal() sometimes expects a particular kind
of side effect. This is totally a design flaw. And it's definitely not
a responsibility of Logger to influence the execution flow of
the program.
