Move the early_data_{offered,reason} logic out of extension callbacks.

ECH requires that we construct two ClientHellos. That means our
add_clienthello callbacks will need to be called multiple times and
should be const. (They already are called multiple times for
HelloRetryRequest, but we currently thread that through the callbacks a
bit. With ECH, I think we need to make them pure serialization.)
