LibWeb: Honor appearance: none when creating input element layout node

Browse Source 
Per css-ui-4, setting `appearance: none` is supposed to suppress the
creation of a native-looking widget for stuff like checkboxes, radio
buttons, etc.

This patch implements this behavior by simply falling back to creating
a layout node based on the CSS `display` property in such cases.

This fixes an issue on the hey.com imbox page where we were rendering
checkboxes on top of sender profile photos.
