Support TLS v1.2 algorithm in SunPKCS11 provider

See the comment in SunPKCS11.java. Need to consider whether we can support SunTls12Prf, SunTls12RsaPremasterSecret, etc. in SunPKCS11 in the future.

        /*
         * TLS 1.2 uses a different hash algorithm than 1.0/1.1 for the
         * PRF calculations. As of 2010, there is no PKCS11-level
         * support for TLS 1.2 PRF calculations, and no known OS's have
         * an internal variant we could use. Therefore for TLS 1.2, we
         * are updating JSSE to request different provider algorithms
         * (e.g. "SunTls12Prf"), and currently only SunJCE has these
         * TLS 1.2 algorithms.
         *
         * If we reused the names such as "SunTlsPrf", the PKCS11
         * providers would need be updated to fail correctly when
         * presented with the wrong version number (via
         * Provider.Service.supportsParameters()), and we would also
         * need to add the appropriate supportsParamters() checks into
         * KeyGenerators (not currently there).
         *
         * In the future, if PKCS11 support is added, we will restructure
         * this.
