SnackBar with action no longer auto-dismiss (#173084) ...

Fixes https://github.com/flutter/flutter/issues/173000

This PR updated the default behavior for Snackbar with action:
* SnackBars no longer auto-dismiss if SnackBar.action is not null.
* To override the default behavior, this PR added a property `persist`
for `SnackBar`.
