Currently, there are multiple functions in ARM64 code that walk the
stack using start_backtrace() and unwind_frame() or start_backtrace()
and walk_stackframe(). They should all be converted to use
arch_stack_walk(). This makes maintenance easier.

To do that, arch_stack_walk() must always be defined. arch_stack_walk()
is within #ifdef CONFIG_STACKTRACE. So, select STACKTRACE in
arch/arm64/Kconfig.
