* Use `ShareIntentHandler` early to avoid distributing the whole intent
This would make the intent be serialized as part of `NavTarget` and could potentially lead to `TransactionTooLargeException`s.
We now pass a new `ShareIntentData` class around, containing the minimum amount of data needed. We also have a new `OnSharedData` post-processor to revoke uri access after they've been shared.
* Move `UriToShare` next to `ShareIntentData` and add docs
