RFR: JDK-6676643: Improve current C_GetAttributeValue native implementation

Tue Apr 27 02:47:46 UTC 2021

Anyone can help review this somewhat trivial fix? The main change is inside src/jdk.crypto.cryptoki/share/native/libj2pkcs11/p11_objmgmt.c. This is to help better troubleshooting by reporting the type of unavailable attributes in PKCS11 exception message when C_GetAttributeValue(...) call failed. The java file changes are just cleanup for consolidating the CKR_* constants definition into PKCS11Exception class.

Thanks,
Valerie
