RFR: 8277976: Break up SEQUENCE in X509Certificate::getSubjectAlternativeNames and X509Certificate::getIssuerAlternativeNames in otherName [v6]

[Weijun Wang]

> The enhancement adds two extra items in the `getSubjectAlternativeNames()` output for an OtherName.
> 
> It also fix several errors:
> 1. In `OtherName.java`, `nameValue` should be the value inside `CONTEXT [0]` without the tag and length bytes.
> 2. The argument in constructor `extClass.getConstructor(Object.class)` is suspicious. Maybe it meant `byte[]`.
