Jamil 889c1a971c fix(apple): Correctly handle stopTunnel and completionHandlers (#9308)
This PR fixes two crashes related to lifetimes on Apple:

- `completionHandler` was being called from within a Task executor
context, which could be different from the one the IPC call was received
on
- The `getLogFolderSize` task could return and attempt to call
`completionHandler` after the PacketTunnelProvider deinit'd
- We were calling the completionHandler from `stopTunnel` manually.
Apple explicitly says not to do this. Instead, we must call
`cancelTunnelWithError(nil)` when we want to stop the tunnel from e.g.
the `onDisconnect`. Apple with then call our `stopTunnel` override. The
downside is that we have no control over the `NEProviderStopReason`
received in this callback, but we don't use it anyway. Instead, we write
the reason to a temporary file and read it from the GUI process when we
detect a status change to `disconnected`. When that occurs, we're able
to show a UI notification (macOS only - iOS can show this notification
from the PacketTunnelProvider itself).
