RFR 8213009: Refactoring existing SunMSCAPI classes

[Weijun Wang]

Webrev updated at

   Asserts.assertTrue(pr.getAlgorithm().equals("RSA"));

More refactorings:

- getEncoded and getFormat of CKey removed, implemented in CPublicKey and CPrivateKey.

- CPublicKey has child class CRSAPublicKey, CKeyPairGenerator has child class RSA.

- CPublicKey and CPrivateKey now have a static of() method that can return a child instance.

- CCipher renamed to CRSACipher. I realized there won't be CECCipher.

Thanks
Max
