QQuickTableView: reposition selection handles whenever TableView updates the layout

After TableView got support for resizable rows and columns, a
side effect is that any overlay, like the selection handles, will
need to be repositioned when rows and columns are resized.
Currenly the selection handles will instead stay put at the
initial location.

This patch will make sure that SelectionRectangle listens to
the layoutChanged() signal from TableView, and reposition the
handles.

Because the current selection rectangle implementation in
TableView didn't take row and column resizing into account
either, the logic that calculates the rectangle is also
changed. Rather than storing the selection rectangle after
each mouse drag, we now calculate the exact (and updated)
rectangle when queried instead.
