arm64: ptrace: add support for syscall emulation Add PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP support on arm64. We don't need any special handling for PTRACE_SYSEMU_SINGLESTEP. It's quite difficult to generalize handling PTRACE_SYSEMU cross architectures and avoid calls to tracehook_report_syscall_entry twice. Different architecture have different mechanism to indicate NO_SYSCALL and trying to generalise adds more code for no gain.
