Remove TestFrameSequence::MetadataBlockForPayload().

Metadata tests compare HeaderBlock(payload) to HeaderBlock(payload). We can
simplify the equation by removing the HeaderBlock() wrapping on both sides.
This change aligns with the header block encoding and decoding of metadata
happening above the nghttp2 extension layer/the OgHttp2Session metadata layer.
This change is also a prefactor for sending empty metadata payloads in tests.

QUICHE stands for QUIC, Http/2, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:
