ca46c67e9e Create YogaValue instances in Java, not C++
Summary:
@public

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.

5bb2265083 Move native methods to a single class
Summary:
@public

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.

f039835249 renamed YogaNodeJNI to YogaNodeJNIBase
Summary:
Renamed class from YogaNodeJNI to YogaNodeJNIBase.
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.

888892885e Encapsulate all used java classes
Summary:
@public

Moves all Java classes used from C++ to their own header + implementation file. In `YGJNI.cpp`, we only call methods on these objects deriving from `jni::JavaClass`.

This is only a bit of cleanup, no functional change.
