HTTP3: fix Windows build
The ngtcp2 QUIC backend was using the MSG_DONTWAIT flag for send/recv
in order to perform nonblocking operations. On Windows this flag does
not exist. Instead, the socket must be set to nonblocking mode via
ioctlsocket.
This change sets the nonblocking flag on UDP sockets used for QUIC on
all platforms so the use of MSG_DONTWAIT is not needed.
Fixes #4531
Closes #4532
