IGNITE-8486: Updated ConcurrentLinkedDeque8 to match the latest version in
JSR 166 repo.

> Update ConcurrentLinkedDeque in Ignite's master repository to the latest JDK

> Key: IGNITE-8486
> URL: https://issues.apache.org/jira/browse/IGNITE-8486
> Project: Ignite
> Issue Type: Improvement
> Reporter: Stanislav Lukyanov
> Assignee: Stanislav Lukyanov
> Priority: Major
>
> Ignite still uses copies of several JSR 166 (j.u.concurrent) classes in it's
> sources. Those copies are now outdated compared to the latest versions used
> in JDK.
> In particular, `ConcurrentLinkedDeque` has received a couple of correctness
> fixes recently (https://bugs.openjdk.java.net/browse/JDK-8188900,
> https://bugs.openjdk.java.net/browse/JDK-8189387). It would be good to have
> them in Ignite as well to protect ourselves from possible issues.
> The task is to update Ignite's `ConcurrentLinkedDeque8` to the latest version
> of `ConcurrentLinkedDeque`, although keeping compatibility with earlier Java
> version (e.g. JDK's version now uses Java 9's VarHandles which we can't use
> yet).
