Enhance SunJCE provider to support SHA-3 based Hmac algorithms

Summary

Enhance SunJCE provider to support SHA-3 based Hmac algorithms.

Problem

No default JDK providers support SHA-3 based Hmac algorithms.

Solution

Enhance SunJCE provider to support SHA-3 based Hmac algorithms, including Mac and KeyGenerator implementations for HmacSHA3-224, HmacSHA3-256, HmacSHA3-384, HmacSHA3-512. In addition, also added KeyGenerator implementations for HmacSHA512/224 and HmacSHA512/256 whose Mac implementation is already made available under an earlier RFE.

Specification

No changes to existing public APIs. These newly supported algorithm names are already documented in the "Java Security Standard Algorithm Names". Only the "JDK Providers Documentation" needs to be updated to add these algorithms as available algorithms for SunJCE provider. In particular, add HmacSHA512/224, HmacSHA512/256, HmacSHA3-224, HmacSHA3-256, HmacSHA3-384, HmacSHA3-512 to the algorithms under "KeyGenerator", and add HmacSHA3-224, HmacSHA3-256, HmacSHA3-384, HmacSHA3-512 to the algorithms under "Mac". Please find the pdf diff of the documentation as attached.
