Decompose transform matrix in native (for android).

Browse Source 
Summary:
This diff translates implementation of transform matrix decomposition from JS to java. This is to support offloading animations of transform property, in which case it is required that we can calculate decomposed transform in the UI thread.

Since the matrix decomposition code is not being used for other platform I went ahead and deleted parts that are no longer being used.

**Test plan**
Run UIExplorer Transform example before and after - compare the results
Closes https://github.com/facebook/react-native/pull/7916
