[MSAFD] Add an initial implementation of SIO_GET_EXTENSION_FUNCTION_P…

…OINTER IOCTL Also stub the related functions the IOCTL will return, namely: WSAID_ACCEPTEX, WSAID_CONNECTEX, WSAID_DISCONNECTEX, WSAID_GETACCEPTEXSOCKADDRS This will allow Steam client not to fail in an ASSERT related to the Steam client PlatformSocketsInit function. Even though, this doesn't fix Steam running on ReactOS since its UI requires a Windows 7 API from Kernel32: SetThreadErrorMode(). Nota: its crash got fixed thanks to the Wine sync done recently.
