[code-reflection] Integrated: removed jextracted opencl dependency on life example

[Gary Frost]

Removed the jextracted opencl dependencies on life example. 

We used the game of life example to prove the algorithm for minimizing buffer transfers using jextracted opencl

Now we seem to have a stable version of the algorithm in HAT itself we can now remove the jexctracted opencl dependency. 

This also means we can build and run on cuda and test the algorithm there.
