MINOR: mux-h1/trace: add a state trace on stream creation/upgrade

Logging below the developer level doesn't always yield very convenient
traces as we don't know well where streams are allocated nor released.
Let's just make that more explicit by using state-level traces. Note that
h1s destruction was already logged as closing connection or switching
to idle mode.
