We missed to sign the handler. Along the way the signature of it
changed, so adjust for that.
How to get the number:
```
func PROPER(bar: (TaskPriority, TaskPriority) -> Void) {
let p = TaskPriority.default
bar(p, p)
}
```
```

Description: the new task priority escalation API was missing pointer auth signing on when we use the handler.
Scope/Impact: Makes withTaskPriorityEscalationHandler usable with pointer authentication.
Risk: Low, this was broken on ptr-auth before, no impact on other code.
Testing: CI testing
