Fix ContentInViewModifier to not read layout coordinates unless attached.

This fix was originally made in aosp/2147367, I'm not sure how it got
removed but probably had something to do with a refactor/rebase while
working on the ContentInViewModifier.

This change should be cherry-picked into the 1.3 release branch.

Fixes: b/244824895
Test: I'm not sure how to write tests for this, but I'm pretty confident
    that this missing check is what is causing the crash.
