Re: [w3c/webcomponents] Events whose composed flag should be true (#513)

cut/copy/paste are defined in https://w3c.github.io/clipboard-apis/

Its interface is
```
interface ClipboardEvent : Event
```

I have taken a look at the spec, however, I do not have any preference whether to add ClipBoardEvent or not. I guess there are different opinions about ClipboardEvent.

It might be good to exclude it as a starting point. If web developers find that it is inconvenient, we can add it without a significant risk, I think.
