Dont create a spacing object for returning margin, padding, border, and position

Browse Source 
Summary: The current implementation was made out of simplicity and to keep the same API as before. Now that the java version of csslayout is deprecated it is time to change the API to make the calls more efficient for the JNI version. This diff with reduce allocations as well as reduce the number of JNI calls done.
