QQuickTableView: don't position the table contents outside the viewport

If you call positionViewAtCell(row, Qt.AlignTop) for the last row
in the table, the row will be aligned to the top of the view, as
requested. But this looks really wrong , since it will cause the
table to be flicked to a position that causes it to overshoot
by a distance close to the height of the whole view, effectively
leaving a big empty gap at the bottom. This looks really buggy.

This patch will correct this behavior by ensuring that we never
flick the table to an "invalid" position while positioning
table at a cell using the requested alignment. Instead we
clamp the table to the edges of the viewport.
