windows.security.credentials.ui.userconsentverifier: Implement
IUserConsentVerifierStatics::CheckAvailabilityAsync().

I've finished implementing this class. For some reason, there's a race
condition happening and it only works consistently when WINEDEBUG=+credentials
is added. I'm not sure why this is happening.

I've attached a patch that you can test yourself. Maybe it's just happening on
my PC. I used a fresh prefix though.
