QNetworkInformation[Win]: Catch potential exceptionsv6.4.16.4.1

Some Windows SDKs seem to throw an exception (sometimes?) when
calling ConnectionProfile::NetworkAdapter.
Catch the exception and ignore it, we would return Unknown anyway.
And just in case it is needed, do the same for GetConnectionCost.

This requires enabling exceptions for the plugin.
