Summary: Apparently we can/should not have in RCTConversions because it creates unnecessary dependency to core iOS module.

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.
