"Fix" for [#33524] Interaction of "Size" & "Distance" sliders in "Spot Lamp" panel with "3D view"

Simply added a dashed line materializing the center/direction of the spot, and ending at Distance from it (exactly as for the Area lamp). We already had something similar for buffered shadow spots (to materialize start/end clipping), and imho it's also quite useful to see *where* points a spot, when using wide spots!

Very easy to revert anyway.
