Re: [PATCH 0/5] MR8222: widl: Add rows for the struct type.

[Rémi Bernon (＠rbernon)]

This outputs rows for the generic interfaces too, whereas the generic types should be outputted only once, as CLR generics.

```
.namespace Windows.Foundation.Collections
{
  .class interface public auto ansi abstract 'IIterator<ABI::Windows::Gaming::Input::ArcadeStick* >'
  {
  } // end of class Windows.Foundation.Collections.IIterator<ABI::Windows::Gaming::Input::ArcadeStick* >
}
.namespace Windows.Foundation.Collections
{
  .class interface public auto ansi abstract 'IIterator<ABI::Windows::Gaming::Input::RawGameController* >'
  {
  } // end of class Windows.Foundation.Collections.IIterator<ABI::Windows::Gaming::Input::RawGameController* >
}
/* etc... */
```

Should be instead one:

```
.namespace Windows.Foundation.Collections
{
  .class interface public auto ansi abstract IIterator`1<T>
  {
     /* interface details, using T */
  }
}
```
