make the initial stream receive window configurable

While the initial window size is defined by the yamux specification
(256 kB), we can just send a window update as soon as a stream is
opened / accepted. In fact, that's exactly what we do already.

set initial window size to spec value (256 kB), remove config option

fix: don't change the receive window if we're forcing an update

Otherwise, our initial SYN/SYN-ACK packet will update the receive window
every time.

sync: update CI config files

Otherwise, we'll get a zero RTT on windows.
