RFR: 8358451: SunJCE PBEKey impl should throw IllegalStateException when getEncoded() is called [v2]

[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.

Valerie Peng has updated the pull request incrementally with one additional commit since the last revision:

  Moved the Key.isDestroyed() check from individual provider SKF impl to
  JCA SecretKeyFactory class.
  Changed to throw ISE whenever destroyed key is encountered.
