Fix a potential nullptr dereference in AppleObjCRuntimeV2 by checking
the result of GetClassInfoUtilityFunction and returning a failure if
it's null.

The DynamicClassInfoExtractor was already doign the right thing, but the
SharedCacheClassInfoExtractor was missing this check.

(cherry picked from commit 957a5e9)
