Let OgHttp2Session avoid visitor callbacks for data on unknown streams.

This CL performs a stream map check in OgHttp2Session::OnDataFrameHeader() and
OgHttp2Session::OnStreamFrameData(). If the stream is not in the map, then
OgHttp2Session will avoid invoking visitor_.OnBeginDataForStream() and
visitor_.OnDataForStream(), respectively. This behavior is in line with
Http2Dispatcher behavior [1, 2] and brings oghttp2 more in line with nghttp2.
Similarly, this CL also moves visitor_.OnEndStream() into an already-existing
stream map check. This behavior also allows
to pass, as hypothesized in http://b/201799377#comment8:

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:

To contribute to QUICHE, follow instructions at CONTRIBUTING.md.

QUICHE is only supported on little-endian platforms.
