After changing native methods to return `long` rather than `YogaValue`, we switch them to JNI fast calls, as there is no more interaction with the Java GC.

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.

Summary:

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.

Contexts of nodes only hold a bit mask after we got rid of weak JNI refs.
We can simply store that data in a pointer-sized unsigned int.
Here, we replace all context heap allocations with usage of the node context (`void *`) as bitmask. We also add a couple of utility operators in order to keep the code comprehensible.

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.

Note that only homogeneous trees are supported, i.e. **mixing weak-ref and non-weak-ref nodes will break!**
