RFR: 8358451: SunJCE PBEKey impl should throw IllegalStateException when getEncoded() is called [v3]

[Valerie Peng]

> Update the `PBEKey` class of the SunJCE provider which override the `javax.security.auth.Destroyable` interface to 
> 
> 1. throw `IllegalStateException` if `getEncoded()` is called after key is destroyed
> 2. serialization of such destroyed `PBEKey` object will lead to exception. 
>  
> Also update the `PBEKeyFactory` class of the SunJCE provider to check for destroyed keys and throw exceptions per the method javadoc.
