[AA] Implement disposable KtResolveExtensions

- This commit adds the `Disposable` interface to `KtResolveExtension`.
  Resolve extensions are disposed after their associated session has
  been invalidated, or reclaimed by the GC.
- Example use case: Opening a message bus connection with the lifetime
  of the resolve extension.
