[screen-wake-lock] Do not use allow="screen-wake-lock" for iframes (#277)

jumde has just created a new issue for https://github.com/w3c/screen-wake-lock:

== Do not use allow="screen-wake-lock" for iframes ==
It would be better to use only `Feature Policy` to determine which third parties have access to screen-wake-lock

```
{"screen-wake-lock": []}
```

Attributes of iframes can be easily modified by javascript. So a simple XSS can enable `screen-wake-lock` for all third-party iframes on a site.
