Summary:
This is the final piece of change that makes measuring (`LayoutableShadowNode::getRelativeLayoutMetrics()`) take ScrollView content offset into account (on iOS).
It works pretty simply: at the end of scrolling (or zooming) action ScrollView updates the state which later can be used for computing `transform` which measuring uses to adjust values in LaoutMetrics.

Summary: Diffing algorithm uses a small map for every layer of shadow tree; that's a lot of maps. Luckily, it does not need a complex feature-full map (which is not free to allocate and use), it needs a tiny map with a dozen values. Why do we need to pay for what we don't use? This diff introduces a trivial map optimized for constraints that we have here. (See more details in the code.)

Summary: Convert FabricUIManager.measure params to floats. Currently we convert parameters to ints across the JNI boundary, and then back to floats several times in Java. This is unnecessary and actually makes measurements trickier. The new implementation uses floats across the JNI boundary and uses Float.POSITIVE_INFINITY to represent unconstrained values, which is consistent with Fabric C++ as well.

Summary:
Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Summary:
Different frameworks use different kinds of floats, optional floats, and floats with assigned unit names. All those approaches use different ways to represent undefined and empty values. To deal with it we need to have some helper functions.
So, this diff changes some ways that we convert some corner values (like NaN and empty value). That change is motivated by recent personal discoveries in this field that shifted my vision on that. E.g. ComponentKit does not use `CGFloatMax` value as `Infinite` value. UIKit is also (surprisingly to me) okay with using `Infitite` instead of `CGFloatMax`. And, in general, seems using really conceptually appropriate values (instead of UIKit-inspired ones) it's the right thing to do.

Summary:
We don't need to have those constants because this functionality is available in STL via `std::numeric_limits<YourParticularFloatType>::infinity()` (or `::min()` and `::max()`).
At the same time usage of `kFloatMax` was replaced with `Infinity` (which is a different value). Using `max` instead of `Infinity` was an attempt to mimic iOS/UIKit model where `Infinity` and `NaN` values usually are not being used. However, now this does not seem like a good idea. This concept is not used anywhere else (even in CK which is totally incompatible with it) and de-facto in RN we use it only in few places. So, let's use Infinity in places where it's logically appropriate.

Summary:

Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.

Apparently, `DEBUG` is non-standard feature and using `assert` with `DEBUG` is practically asking for bugs. So, if your `assert` relies on some variable which is only defined when `DEBUG` is set, it's easy to get invalid code because NDEBUG and DEBUG can be unsync.
So, we have to use clunky double negative `#ifndef NDEBUG` everywhere where we used DEBUG.

Summary:

In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.
