Ability to add some meta for Destination

[TemMax]

Hello! Sometimes, I need to wait for the result from some screen with an assigned "action_id." For example:

1. Screen A opens screen B using navigator.navigate(BDestination(params = BParams(action_id = "123"))).
2. Screen A waits for the result using:
   bResultRecipient.onNavResult { result -> ... }
3. Screen B was closed by swipe (for example, it was a bottom sheet)
4. bResultRecipient will receive the NavResult.Canceled event, but I can't determine which action_id it was

The only possible way to do it for now is to execute this code once on screen start:
navigator.setResult(BResult.Canceled(action_id))

In this case, when the swipe closes the screen, I won't receive a NavResult.Canceled event.

Generally, it looks good, but maybe there are some points that need improvement.
