This adds support for the STACKLEAK gcc plugin to arm64 by implementing stackleak_check_alloca(), based heavily on the x86 version, and adding the two helpers used by the stackleak common code: current_top_of_stack() and on_thread_stack(). The stack erasure calls are made at syscall returns. Additionally, this disables the plugin in hypervisor and EFI stub code, which are out of scope for the protection.
