Carl Mastrangelo e96c37dea7 Disable Huffman encoding for small headers (#9260 )

Motivation:

Huffman coding saves only a little space, but has a huge CPU cost

Modification:

Disable huff coding for headers smaller than 512 bytes.  Also, add a
configurable limit to the encoder.

Result:

Faster HPACK
