The separate geometry and delete geometry nodes often invert the
selection so that deleting elements from a geometry can be implemented
as copying the opposite selection of elements. This should make the two
nodes faster in some cases, since the generic versions of selection
creation functions (i.e. from d3a1e9cbb9) are used instead
of the single threaded code that was used for this node.
The change also makes the deletion/separation code easier to
understand because it doesn't have to pass around the inversion.
