Move all handling of HTTP's `Expect: 100-continue` feature into a client reader. Add sending flag `KEEP_SEND_TIMED` that triggers transfer sending on general events like a timer. HTTP installs a `CURL_CR_PROTOCOL` reader when announcing `Expect: 100-continue`. That reader works as follows: - on first invocation, records time, starts the `EXPIRE_100_TIMEOUT` timer, disables `KEEP_SEND`, enables `KEEP_SEND_TIMER` and returns 0, eos=FALSE like a paused upload. - on subsequent invocation it checks if the timer has expired. If so, it enables `KEEP_SEND` and switches to passing through reads to the underlying readers. Transfer handling's `readwrite()` will be invoked when a timer expires (like `EXPIRE_100_TIMEOUT`) or when data from the server arrives. Seeing `KEEP_SEND_TIMER`, it will try to upload more data, which triggers reading from the client readers again. Which then may lead to a new pausing or cause the upload to start. Flags and timestamps connected to this have been moved from `SingleRequest` into the reader's context. Closes #13110
