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.

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.

Completely removes the usage of weak JNI refs.
This is great, because node allocation and deallocation no longer go through a VM-global lock to access the weak reference table.
This is also great, because we can no longer overflow that ref table.
Performance is comparable to weak refs.

Summary:
Added a new API `YGNodeSetLayoutStyleInputs` to pass layout style inputs from java to native code.
All the style inputs are passed in a float array in [key1, key2, value2, key3, value3a, value3b .....] format over JNI layer.
There are three types of style inputs
- do not need any value to be passed along with them like WidthAuto, HeightAuto
- need one value to be passed like Width, Height
- need two values to be passed like Margin, Padding (edge value and actual margin, padding value)

Adds the ability to opt into avoiding global weak JNI refs via `YogaConfig`.
Note that only homogeneous trees are supported, i.e. **mixing weak-ref and non-weak-ref nodes will break!**
Not using JNI refs hopefully will help with avoiding JNI reference table overflows, and will help creating trees on multiple threads, as no lock has to be acquired at any time.

This diff includes the following changes:
1 ) I extended the Java implementation of YogaNode to be able to get a full copy of a YogaNode object without copying the List of children of the original YogaNode. In other words, the new copy of the YogaNode will have the same data of the original YogaNode, but with an empty list of children.
2 ) We created a new method in Yoga.cpp called YGNodeInsertSharedChild. This new method is going to be used by Fabric in order to temporarily share a YogaNode between two "Yoga Trees" (the "current Yoga" tree and a partial "clone of the current Yoga tree"). We exposed this new functionality in the java implementation of Yoga (method addSharedChildAt)

Summary:
Changed NaN with large number to support `-ffast-math` compiler flag.For `-ffast-math` to work, all floating point numbers should be finite. Reason for not going with `FLT_MAX`, is that, it may cause number overflow during math operations. So thats why I opted for big number smaller than `FLT_MAX`. Earlier we used NaN, while NaN is involved in comparision the comparision operator behaves differently, it always returns false. Also operators like, fmaxf,fminf etc. have wierd beahviours. This diff takes care of those things as far as possible, and all tests are passing.
