Extra log for case where availableHeight is undefined and sizing mode…

… != max content (#1687)

Summary:
X-link: facebook/react-native#45965

Pull Request resolved: #1687

We are seeing some crashes that are hard to wrap our head around. Lets add more logs. I chose these values based on what could make the height/width undefined from looking at the code. We might need more but this should give us some more direction.
