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().

On some architectures/simulators it is difficult to provoke an
exception with misaligned or illegal data loads. Use an illegal
instruction instead.

This helps to reduce the use of architecture-specific defines throughout
the code base.

The context validation support functions _CPU_Context_validate() and
_CPU_Context_volatile_clobber() are used only by one test program
(spcontext01). Move the function declarations to the CPU port
implementation header file.

This addition allows us to successfully run the sample hello.exe test.
Updates #2898.

Current state:
- Basic context initialization and switching code.
- Stubbed console (empty functions).
- Mostly functional linker script (may need tweaks if we ever want to move
away from the large code model (see: CPU_CFLAGS).
- Fully functional boot, by using FreeBSD's bootloader to load RTEMS's ELF for
UEFI-awareness.
In short, the current state with this commit lets us boot, go through the system
initialization functions, and then call user application's Init task too.
Updates #2898.
