MdePkg RVCT: add definition of UNREACHABLE
The RVCT compiler in --gnu mode appears to simply strip of the __builtin
prefix when it encounters calls to __builtin_xxx() functions, and so
the __builtin_unreachable() we emit for GCC results in linker errors
regarding undefined references against 'unreachable()'.
So define UNREACHABLE() to a NOP instead.
