Add `max_header_bytes` to OgHttp2Session::Options() and send in initial SETTINGS.

This configurable option allows OgHttp2Session's HPACK decoder to adjust its
decoding buffer size and max allowed header block size in a similar strategy to
Http2Dispatcher [1]. This change is important to allow OgHttp2Session to decode
headers following Envoy's `max_headers_kb_` [2].

When locally added to Envoy's Http2Options [3], this change allows the
following codec_impl_tests to pass: LargeRequestHeadersAtLimitAccepted,
LargeRequestHeadersInvokeResetStream, LargeMethodRequestEncode,
LargeRequestHeadersOverDefaultCodecLibraryLimit (arguably no longer needed),
LargeRequestHeadersAtMaxConfigurable, LargeRequestHeadersAccepted.
