optimize getNativeProps method 

Summary:
The original method getNativeProps in ViewManagerPropertyUpdater.java create more HashMaps and putAll method need to re-hash the key again to avoid conflicts. This pull request pass the map as params to avoid the problem and update ReactPropertyProcessor.java to adapt the change.
