check_bool<T> should return T

Today, winrt::check_bool<T> returns void. There are some Win32 APIs that return 0 on failure and a valid result on success eg: [GetFileVersionInfoSizeW](https://learn.microsoft.com/en-us/windows/win32/api/winver/nf-winver-getfileversioninfosizew) so having winrt::check_bool<T> returning T would be convenient while using them.
