QmlDesigner: MoveGizmo improvements in 3D edit view

Browse Source 
Mouse press and release are now properly handled by MouseArea3D.
This fixes various issues:

- No need to move the mouse after release for release to register.
- Drag is no longer limited to the 3D edit window, though it is still
  limited to the screen.
- Drag arrows no longer register start of drag if you click outside
  the arrow and then move the cursor over the arrow while holding the
  mouse button down.

Also added the missing center ball to the MoveGizmo to allow free
dragging along the camera plane.
