internal/http3: return error when Write is used after status 304 is set

In our HTTP/1 and HTTP/2 implementations, calling Write in a server
handler after WriteHeader has been called with status 304 will return an
http.ErrBodyNotAllowed error. This change adds the same behavior for the
HTTP/3 server.

For golang/go#70914
