WinIO: Small changes related to atomic request swaps.
Move the atomix exchange over the Ptr type to an internal module.
Fix a bug caused by us passing ptr-to-ptr instead of ptr to
atomic exchange.
Renamed interlockedExchange to exchangePtr.
I've also added an cas primitive. It turned out we don't need it
for WinIO but I'm leaving it in as it's useful for other things.
