Changelog: [internal]
This is a life cycle issue where LayoutManager outlives the runtime. To fix this, we need to destroy `_accessibilityProvider` before the runtime. The way to do it is to destroy it inside `prepareForReuse` which is guaranteed to be called before runtime is destroyed.

Summary:
Now we check for `_state` being nullptr before dereferencing this.
`accessibilityElements` (as a bunch of other methods that have the same check) can be called by OS any moment (we cannot predict when), so at some very rare moments, it can be called when the view is not fully initialized yet. To prevent crashing we just need to return some default value indicating that the view is empty.

[Internal] - Fix the frame issue for truncated text.
When double tapping to expand/truncate the text, the rect of the element always moves to the top and then come back to the original place.. This seems because after truncating/expanding the text, the view would re-render and the container would be destroyed. I used the API accessibilityFrameInContainerSpace to set the frame before. And the frame was not updated properly. Converting the bound to the screen coordinates and set accessibilityFrame directly fixed it.

Summary:
We don't know why exactly it happens but (seemingly) sometime Paragraph component receives an empty State object. This causes a crash because of unchecked access to an instance variable.
This diff introduces an assert in DEBUG mode and the check for prod.
Why is this happens? Hard to say, probably `layout()` method (which updates `State`) is not being called on ShadowNode. Why? One explanation can be that Yoga skips some subtree during layout because it starts from "visibility: hidden" component. We need to investigate it more and figure out what exactly going on and what should we need to improve besides the check. That's why we have an assertion.

Summary:
In some cases, the view class is the only that retains stored `props_` variable. At the same time the `[super updateProps:props oldProps:oldProps];` actually resets the pointer with a pointer to new props value which sometimes causes the deallocation of the old value. All that is okay unless the implementation of `updateProps:oldProps:` in superclasses stores a raw reference to an old value in the very beginning of the method (for convenience and perf reasons).
So, to prevent preliminary deallocation of the old value pointed by `_props` we moved all `[super updateProps:props oldProps:oldProps];` calls to the end of overloaded methods.

Summary:
ComponentDescriptorProvider represents unified way to create a particular descriptor.
Now all ComponentViews (which support RCTComponentViewProtocol) expose a `ComponentDescriptorProvider` which will allow creating and registering ComponentDescriptor instances for all visual components automatically as a part of ComponentView registration process.
Don't panic, everything is still being as explicit as it always was, no magic involved; we just will have only one registration step instead of two parallel.
That also opens a way to register components on the fly.

Summary:
Previously, we stored a pointer to ShadowNode inside NSAttributedString's attributes to make possible retrieving an EventEmitter associated with some text fragment.
That worked fine besides only one caveat: the internal implementation of NSAttributedString is quite strange and that causes a memory leak. Because of some reason, NSAttributedString does not release stored attributes after own destruction (maybe OS uses some kind of caching).
So, now, instead of storing a strong pointer to ShadowNode inside NSAttributedString, we store a weak pointer to EventEmitter. Storing a weak pointer is okay because a desired lifetime of EventEmitter is guaranteed by LocalData stored inside a View. Storing a weak EventEmitter instead of weak ShadowNode will also help us with migration to ShadowView (we cannot store ShadowView weakly because it's a stack allocated object).
