Description of how this works in `docs/internal/RATELIMITS.ms`. Notable implementation changes: - KEEP_SEND_PAUSE/KEEP_SEND_HOLD and KEEP_RECV_PAUSE/KEEP_RECV_HOLD no longer exist. Pausing is down via blocked the new rlimits. - KEEP_SEND_TIMED no longer exists. Pausing "100-continue" transfers is done in the new `Curl_http_perform_pollset()` method. - HTTP/2 rate limiting implemented via window updates. When transfer initiaiting connection has a ratelimit, adjust the initial window size - HTTP/3 ngtcp2 rate limitin implemnented via ack updates - HTTP/3 quiche does not seem to support this via its API - the default progress-meter has been improved for accuracy in "current speed" results. pytest speed tests have been improved. Closes #19384
