wasm: fix qtloader.js container element regression

As of Qt 6.5 the html document should not create canvas
elements directly, but instead create div container
elements and let Qt create and manage the canvas elements.

However, qtloaders.js has not been updated to match this
and is still creating canvas elements when given div
elements.

Remove the canvas creation code and invert the primary
and fallback case: config.containerElements is now passed
to instance.qtContainerElements. config.canvasElements
is copied to config.containerElements, if set.
