feat(windows): add error code from async operation

[acouvreur]

With the addition of IAsyncInfo in winrt-go: saltosystems/winrt-go#118

We can now extract the actual asynchronous operation error code.

Before:

write device name: failed to write device name: async operation failed with status 3                                                                            

After:

write device name: failed to write device name: async operation failed with status 3: HRESULT 0x80070005                                                                                

This bug report is from my actual code, I have yet to investigate why I get a HRESULT 0x80070005 😄

But, I can actually debug it now.
