iabdalkader b9c1e4c205 drivers/ninaw10: Connect to WiFi asynchronously. 
Before this patch, WiFi connection was blocking, and could raise exceptions
if the connection failed for any reason (including timeouts).  This doesn't
match the behavior of other WiFi modules, which connect asynchronously, and
requires handling of exceptions on connect.  This change makes `connect()`
work asynchronously by scheduling code to poll connection status, and
handle reconnects (if needed), and return immediately without blocking.
