LibOverride: Do not write Laplacian Deform modifier binding data. 

Skip writing binding data and similar for override modifiers already
present in reference linked data, as this can use a lot of space, and
is fully useless data typically since we already skip writing Mesh
geometry data itself.

Ref. T97967.
