This is follow up for D8601600 and D8247652 (the last one has detailed explanation of the problem).
From this commit I propose that we have to follow simple rule:
If some prop has a default value which differs from the default value of its type, we have to specify it as {<value>} in .h file and explicitly in .m file, for all other props the default value must not be specified explicitly (in .h files it must be specified as {}).
The reason is that we have to embrase those cases and establish behaviour: if we change the default value in .h file, it always means that we have to change the value in .cpp file too.

Summary:

The current Fabric architecture, in general, does not support "subscribing" for events, so all kinds of events are always delivered no matter have JavaScript components `on`-handlers for them or not.
At this point, we are not sure should it be this way or not. But we are sure that for some extremely noisy events (like onLayout) we have to make an exception right now (otherwise overall performance will suffer).
So, this diff implements that for `onLayout`.

If some prop has `std::vector` type, it possible that on JS side we want to pass just one element of the array.
And in this case we sometimes drop array initialization (`[]`) part, so instead of passing `[{x:1, y:1}]` we pass `{x:1, y:1}`.
This diff adds support for that.

After reading about move-semantic and rvalue refs I realized that we (I) definitely overuse `auto &&` (aka universal reference) construction. Even if this is harmless, does not look good and idiomatic.
Whenever I used that from a semantical point of view I always meant "I need an alias for this" which is actually "read-only reference" which is `const auto &`.
This is also fit good to our policy where "everything is const (immutable) by default".
Hence I change that to how it should be.

This diff changes how we store and manage Yoga Config in layoutable shadow nodes.
Previously we have `shared_ptr` to single shared yoga config (one to many relationships); now we initiate and store yoga config with yoga node (one to one relationship).
Cons:
- Less memory efficient.
Pros:
- Much more flexible model. Configuration can be tweaked on a per-node basis.
- More performant. Dealing with `shared_ptr` is expensive because of atomic ref-counter. (This is not really applicable for the previous approach but would be applicable for any alternate approach where we want to have more granular control of the configuration.) Data locality is also great in the new model which should positively impact performance.
- Simplicity. Any alternate approach where we manage sets of nodes which share the same configuration is going to be quite complex.

Summary:
During transforming raw prop (`rawProps[<prop>]`) to typed props (`MyProps.<prop>`) we can face three different cases:
* `rawProps` collection has proper serialized value for the key. In this case, we have to set a new value of the typed prop converting value using `fromDynamic`.
* `rawProps` collection does not have value for the key. In this case, we have to copy a value from source prop (`sourceValue`).
* `rawProps` collection has `null` value for the key. This is the special case which means that the prop was removed from the particular component instance and we have to reset it to some *default* value (which is *not* the same as `sourceValue`). Now the default value of the `defaultValue` (sic!) argument is a default value of the type of the value (which may be different from logical default value).
We didn't handle the last case previously and this caused crashes (and unexpected behavior) because `fromDynamic` often cannot handle `null` value.
And yes, all this mean that we also have to update all `convertRawProp` call sites where logical default values are not equal to type-specific default values. This is a potential error-prone place, especially because now we have to specify logical default values in two places (in a prop declaration and in a parameterized constructor). And seems there is no way to avoid that without performance loss (because both of those places are basically constructors).
My hope is that codegen (where default values are also defined in JavaScript) will help with it eventually.
