RFR: 8242332: Add SHA3 support to SunPKCS11 provider

[Valerie Peng]

Could someone please help review this RFE? SunPKCS11 provider is updated with SHA-3 support, including MessageDigest, Hmac Mac, DSA/RSA/RSASSA-PSS/ECDSA Signature, and Hmac KeyGenerator.

As SHA-3 can be used as drop-in replacement for SHA-2 which are already supported by SunPKCS11 provider, the changes for MessageDigest, Mac, and Signature are straightforward. P11KeyGenerator class is updated to support general Hmac key generation including SHA-3 and more. 

While testing against NSS 3.57, there are some unexpected NSS errors with CKM_ECDSA_SHA[224/256/384/512/3_224/3_256/3_384/3_512] and CKM_DSA_SHA[224/256/384/512/3_224/3_256/3_384/3_512], so I disabled those mechanisms in the NSS config file for regression tests. For ECDSA signatures, SunPKCS11 provider will fallback to CKM_ECDSA and do the digesting ourselves.

Thanks,
Valerie
