wasm: set viewport size to device size on mobile 

This is a good default, and also works around a couple
of current bugs in the Qt implementation. (Applications
can change the default values in the .html file as
needed.)

Change body height to 100% of the visual viewport (“100vh”)
to make the html body cover 100% of the viewport after
landscape -> portrait transitions on iOS.

Pick-to: 5.15
