Re: [w3c/manifest] Add a way to query whether there is a UA-provided back button (#693)

Example is a non-fullscreen PWA with nav docked to bottom yet the browser has its navbar also in the bottom. This can lead to serious usability issues, and is a fairly common issue on iOS, not sure about Android.

The browsers navigation UI could be a CSS "predefined environment variable" for web authors to access, see: https://github.com/w3c/csswg-drafts/issues/2630#issuecomment-397536046
