Expose a way to determine if a text node will truncate for a given constrained size #trivial (#1177)
* Expose textLayoutForConstraint:

- Expose textLayoutForConstraint:, but make unavailable on ASTextNode
- Refactor compatibleLayoutWithContainer:text: into a static method

* Instead of textLayoutForConstraint: expose shouldTruncateForConstrainedSize: in ASTextNode
