<i18n dev> RFR: 8363925: Remove unused sun.nio.cs.ArrayEncoder::encode [v2]

[Volkan Yazici]

> [JDK-6636319] introduced `ArrayEncoder`, composed of _only_ `encode` method. Later on [JDK-8054307] (JEP 254: Compact Strings)  removed all its usages. This method can safely be removed, hence this PR. Confirmed that `tier1-2` tests are clear on several platforms after changes.
