Wayland: Improve handling of pending data offers
The code assumed that all data offers were selections that supported plaintext UTF-8. The initial data offer events are now handled almost tolerably. Only selection data offers are used for clipboard string and only if they provide plaintext UTF-8. Drag and drop data offers are now rejected as soon as they enter a surface. Related to #2040
