Summary:
In ContextContainer, only in Debug mode, we store type information alongside with data to detect typemismatch in runtime. We used type hashes before, but seems they are not so stable and can cause some false negative crashes.
This diff changes that to store mangled typenames instead of hashes, so it should be much more reliable now.

Summary: Sometimes we don't know for sure if `ContextContainer` has a value or not (and that's perfectly legit use case). In those cases now we can use `findInstance` method that returns an optional intead of throwing an exeption.

Summary:
`SharedFunction` implements a pattern of a shared callable object that contains the same executable inside. It's similar to `std::function` with one important difference: when the object is copied, the stored function (and captured values) are shared between instances (not copied).
`SharedFunction` can be stored inside `std::function` because it's callable.
It useful in some scenarios, such as:
* When captured by `std::function` arguments are not copyable;
* When we need to replace the content of the callable later on the go.
We will use it in the coming diffs.

Summary: Use a folly LRU implementation to cache results of ParagraphShadowNode::measure, which Yoga asks for repeatedly. Should have a substantial speed improvement on Android and iOS, or at least that's the dream.
