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.
https://github.com/httpwg/http-extensions/pull/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.
