multi: reduce Win32 API calls to improve performance 
1. Consolidate pre-checks into a single Curl_poll call:

This is an attempt to restructure the code in Curl_multi_wait
in such a way that less syscalls are made by removing individual
calls to Curl_socket_check via SOCKET_READABLE/SOCKET_WRITABLE.

2. Avoid resetting the WinSock event multiple times:

We finally call WSAResetEvent anyway, so specifying it as
an optional parameter to WSAEnumNetworkEvents is redundant.

3. Wakeup directly in case no sockets are being monitoring:

Fix the WinSock based implementation to skip extra waiting by
not sleeping in case no sockets are to be waited on and just
the WinSock event is being monitored for wakeup functionality.
