Fix compilation of base for arm64

Add support for the architecture to build/build_config.h (define
new macro ARCH_CPU_ARM64 to identify the CPU architecture and
set the other appropriate macros to 1).

Fix DEBUG_BREAK_ASM() macro to expand to the correct instruction
on arm64 cpu (as instruction set is not compatible with previous
version of ARM instruction sets).
