Unwind from Shadow Call Stacks, only available on arm64.
It's inherently unreliable to unwind from a shadow call stack, because
1) The shadow call stack provides nothing other than return addresses, so it's not possible to
unwind the following frames with other unwinders.
2) A function can choose not to implement shadow call stack, e.g. a library compiled without
SCS, and the unwinder has no way to detect; those frames will be dropped silently.
