David Aurelio 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.
