Schematic decorations: Add 'place_offset_y' placement parameter

Browse source 
For precise control of schematic vertical position relative to the
'place_on' node.
Avoids workarounds that add empty nodes to a schematic and therefore
reduce performance.

Also remove long-unused decoration cutoff code.
