Add Backspace key handling in CreatePolygonObjectTool::keyPressed()
Remove last placed point during polygon/polyline creation
Support both creating and extending modes
Update overlay polygon and handles appropriately
Cancel object when reduced to single point (minimum 2 points required)

Fixes TODO comment about Backspace functionality for going back one step.

Include QKeyEvent.
Don't call updateHandles() and synchronizeOverlayObject() in extending mode, because this already happens as necessary in CreatePolygonObjectTool::objectsChanged.

Ignore Backspace in extending mode when only two points remain to avoid invalid one-point polylines. Also document Backspace support in NEWS and manual keyboard/object editing sections.
