Move QFileSystemModel into QtGui

This requires a QAbstractFileIconProvider in QtGui, as the standard
QFileIconProvider depends on QStyle, and cannot be moved out of
QtWidgets.

QAbstractFileIconProvider returns strings for file types, but returns
no icons yet. Support for a default icon set might be added in a
follow-up commit.
