What `AttachExternalCancellation(token)` does?

See original GitHub issue

Every UniTask instance has a method called AttachExternalCancellation which takes a cancellation token.

How this method works and when should we use it?

inside of UniTask.Create is internal task, external cancellation does not stop it as document described.

In the example you have a method (the lambda) that itself is awaiting tasks (delay). then you have the outer method that is creating a task wrapping the lambda.

if you attach an external cancellation, the outer method is allowed to continue and handle the cancelled operation, however the lambda and any tasks awaited on within do not get the cancellationToken and thus cannot be cancelled this way.

@neuecc I am curious if this is a good way to use a UniTaskCancellationSource that is awaited by multiple users which each want to abort waiting on it at different times?
