Hwnd not marshalled correctly for x86

[angelazhangmsft]

Describe the bug

The new COM interop APIs result in this exception when running on x86 and with passing hwnd as a parameter:

An unhandled exception of type 'System.AccessViolationException' occurred in Microsoft.Windows.SDK.NET.dll
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

To Reproduce

var hwnd = WinRT.Interop.WindowNative.GetWindowHandle(this);
await Windows.Security.Credentials.UI.UserConsentVerifierInterop.RequestVerificationForWindowAsync(hwnd, "Test Message");

Expected behavior

No exception

Version Info

Microsoft.Windows.SDK.NET.dll 10.0.*.18
