winrt: Implement missing SSL socket methods

Move from a stub to a functional SSL socket implementation.

This implementation has some limitations. Due to the way the native
SSL upgrade works, it is not possible to ignore SSL errors after the
handshake has begun. The user must set the ignore flags before
connecting to the host.

Due to missing implementation in the underlying native socket, the
synchronous methods (waitForConnected(), waitForDisconnected()) are not
functional either. Users must rely on the asynchronous methods instead.
This is not a problem in the general case, as HTTP(S) is not affected.

SSL server sockets are not supported by the native API, so it is not
possible to bind an SSL server socket.
