Implement better HPACK Huffman code decoder.

Implement better HPACK Huffman code decoder.

HpackHuffmanDecoder uses less memory and decodes faster (around 30% CPU
reduction in micro benchmark) than previous HpackHuffmanTable decoder.  It is
hard coded; i.e., it cannot decode arbitrary codes, but since the
standardization process is complete, that does not seem necessary.
