Use the new "dcb" and "dcz" content encodings of Compressed Dictionary
The spec of Compression Dictionary Transport has been changed to use
new dcb and dcz content encodings.
httpwg/http-extensions#2784
To follow the spec change, this CL changes the Chromium implementation
and tests as follows:
- Use "dcb" content encoding name instead of "br-d".
- Use "dcz" content encoding name instead of "zstd-d".
- Remove the "Content-Dictionary" response header.
- Check the magic number and the sha256 hash in the head of the
Dictionary-Compressed streams using
SharedDictionaryHeaderCheckerSourceStream. - Re-generate test files using the new content encodings.
