Fixed duplicate QMoveEvent generated for each QWidget::move call

Removed QMoveEvent generating code from QWidgetPrivate::setGeometry_sys
for widgets with native window handles. A move event is already
generated for them by QGuiApplicationPrivate::processGeometryChangeEvent.

Fix sorted QSortFilterProxyModel filter update

When changing a filter so that a previously empty proxy model becomes
populated sorting was not applied correctly.

This was caused by using mapToSource for getting source_sort_column
from proxy_sort_column. For an empty proxy model this won't work because
no valid proxy index can be created in this case.

We now directly use the root index column mapping instead by doing
essentially the same as QSortFilterProxyModelPrivate::proxy_to_source
but without the sanity checks needed for external use.

The sorting feature of QSortFilterProxyModel has always assumed that
the number of columns is specified by columnCount(QModelIndex()) so
the behavior doesn't change.

[ChangeLog][QtCore][QSortFilterProxyModel] Fixed sorting when a
previously empty proxy model becomes populated because of a change in
the filter.
