Adds modsecStatusEngineCall to standalone API

In ModSecurityIIS the configuration is loaded upon the first request
is received. In other words, SecStatusEngine value can be only
loaded once the first request hit the server, and so, the status
function was moved to proceed just after the configuration got loaded.
This update is IIS only.
