score: Canonicalize _CPU_Fatal_halt()

Move _CPU_Fatal_halt() declaration to <rtems/score/cpuimpl.h> and make sure it
is a proper declaration of a function which does not return. Fix the type of
the error code. If necessary, add the implementation to cpu.c. Implementing
_CPU_Fatal_halt() as a function makes it possible to wrap this function for
example to fully test _Terminate().
