Summary: We send conn close packets when network is un-rechable, this task fixes the issue and we no longer send conn close frames when network is un-rechable.

Summary:
Becuase closeImpl will write again. Ideally in this case we should just
abandon the connection, but putting this bandage to prevent crash for now

Summary:
Close the socket when fatal error occurred. This prevents quic transport from receiving readCallback from a bad socket.
Also, close the happy eyeball socket when transport is shutdown.

Summary:
Previously we decided to be conservative and error out the connetion
when either of the 2 sockets fails to write. This makes the happy eyeballs
component meaningless for e.g. IPv4 only network cases. This time we try to do it right.
The connection will keep track `shouldWrite` bool for both sockets. `shouldWriteToFirstSocket` is initialized to true and `shouldWriteToSecond` is initialized to false. Whenever **fatal** error occurs on a socket, the corresponding `shouldWrite` bool is changed to false. We are not finishing happy eyeballs state immediately but delaying this action to when we receive data back.

Summary:
Previously we tried continue on network down and it showed good
improvement. But there was a problem: it hurts UX for airplane mode users, it
didn't return error back to user immediately but after 30/60 seconds timeout.
This adds a timer for this feature and it only allows the transport to ignore
network unreachable error for 200ms. After 200ms, it throws and reports to user
if the error persists.
