I would like to get rid of implicit conversions between `YGValue` and `CompactValue`, because they don’t come for free.
That’s why I am adding `CompactValue` specific overrides for `YGResolveValue` and `YGValueEqual`, that do explicit casts. Up the commit stack, we will be able mark both `CompactValue(const YGValue&)` and `CompactValue::operator YGValue()` as `explicit`.

Passing primitive data via JNI is more efficient than passing objects.
Here, we avoid creating `YogaValue` (Java) instances via JNI, and rather pass a `long` back to Java. The instance is then created by extracting the necessary bytes on the Java side.

Moving all native methods in a single class provides the benefit of not having to load native bindings eagerly when just creating config objects in the startup paths, or setting Java-only values on them.
Loading native bindings triggers additional class loads (`YogaConfig` / `YogaNode`), and can lead to problems in multi-dex scenarions.

This change set is for adding experiment for layout outputs batching using a float array where we will have two separate classes which will override how layout outputs are transferred to java YogaNode object.
We needed two separate classes because having everything in one class was causing memory issues as both the individual fields for width, height etc. and float array for batching needs to be present in code.

Having assignment operators for `YGNode` means that existing children on the node assigned to would have to be handled somehow.
Deallocating might be incorrect. Ignoring might leak.
Here, we `delete` copy assignment, and make move assignment private (it is used in `YGNode::reset()`).
Copy and move constructors *can* be implemented. The move constructor has to take ownership of the children, while the copy constructor leaves ownership untouched. Since children are copied lazily during layout, this does not expose true value semantics. We should consider removing the copy constructor, too.

Summary:

Limit child cloning to layout calculation. This also allows for mixing shared and owned children.
Rationale:
We do allow for shared children if the caller manages themselves. The single known use case is React Native.
So far, we have cloned children eagerly whenever child lists are mutated, or layout is run. This was to allow for a quick check of the owner of any first child, assuming that either *all* or *no* child of a node are shared.
For Yoga/Java, we want to get rid of global weak JNI refs, and these are also used to invoke clone callbacks. We can achieve that goal by switching to an alternative approach, passing additional data to the layout pass. This additional data has to be passed to any configured cloning callback. Therefore, it is desirable to **only call cloning functions during the layout pass.**
The obvious solution seems to be to not uphold the invariant of the first child determining shared/owned state of all siblings, and allow for a mix of shared and own children.
