wasm: Fix handling of native windows

There are two problems
1) internal (not toplevel) windows needs to have the frameLess attribute
set. Without this attribute the window is not visible

2) The backingstore needs to use the correct window, if not the
symptoms are that the display is not always correctly updated.

Seen in the qtdoc/examples/demos/documentviewer demo

Fixes: QTBUG-125856
