gfe-relnote: Fix a bug in QuicSpdyClientStreamBase. Protected by --gfe2_reloadable_flag_quic_eliminate_static_stream_map_3

When eliminate_static_stream_map is true, GetSpdyDataStream() will be called with a stream id that may not be a spdy stream. This results in an invalid cast which blows up in some Chrome tests. I've added a DCHECK in GetSpdyDataStream() to make sure we never do this again, and have added and IsStaticStream() method which can be used for checks in this case. Renames gfe2_reloadable_flag_quic_eliminate_static_stream_map_2 to gfe2_reloadable_flag_quic_eliminate_static_stream_map_3.
