RFR: 7902982: jcstress: Add samples for some mutex algorithms [v2]

[Michael Mirwaldt]

> I have implemented 3 more samples:
> *) the NoAlgorithm sample should show users of JCStress how they can define a critical section in a simple way
> *) one sample for the Peterson's algorithm 
> *) one sample for the Dekker's algorithm 
> I have translated the pseudo code implementations of the English wikipedia articles to Java.
> I have also tried out those examples: they compile and they run without any problems.
