[PATCH] headers: move EventHandler delegate in windows.foundation.idl

[Steve Lhomme]

It's in the .NET System namespace which translates to the Windows.Foundation
namespace in winrt interfaces.

Hi Steve!

This would make EventHandler<T> and EventHandler_impl<T> be generated to 
windows.foundation.h, and I don't think they should go there.

The type is indeed from the Windows.Foundation namespace, but the 
template is available from the windows.foundation.collections.h header 
file, where the current Wine IDL defines it.

Does it cause any issue?

Cheers,
