iOS: add support for adding mimetypes other than text on the clipboard

A QVariant can only be converted to a QByteArray if it has user type
QMetaType::QByteArray or QMetaType::QString. The way it stood, we
always tried to convert the mime data to a QByteArray, and
then put the result into a QVariant. This would fail if the mime
data contained e.g a QPixmap.

This patch will inspect what kind of data the QMimeData contains, and
convert it to a QVariant using the expected API.
