permissive C++ code in windows specific files

The Microsoft C++ team uses the latest Qt build as part of our 'real world code' compiler tests. When testing language conformance improvements in the compiler I noticed a few places that will need to change if you use the new /permissive- switch. I am unable to do a pull request because I don't have a corporate contribution license, so instead I am writing a bug with a suggested fix.

Issue 1) Losing const qualifier from string literal (also covered under /Zc:strictStrings)
src\systeminfo\windows\qwmihelper_win.cpp
Line 138:
hres = wbemServices->ExecQuery((BSTR)L"WQL", bstrQuery, //add cast
WBEM_FLAG_BIDIRECTIONAL | WBEM_FLAG_RETURN_IMMEDIATELY,0,&wbemEnumerator);

Line 293
hres = wbemServices->ExecNotificationQueryAsync(
(BSTR)L"WQL", //add cast
bstrQuery,
WBEM_FLAG_SEND_STATUS,
NULL,
pStubSink);

Issue 2) The MSVC compiler extension to treat copy initialization as direct initialization is disabled under /permissive-
qnetworkinfo_win.cpp line 1082
for (uint i = 0; i < ssid.uSSIDLength;i++) {
QString temp ( ssid.ucSSID[i] ); // {} initialization also fixes it
netname += temp;
}
