Adds to output_geo any missing attributes from source or target as needed. Also optionally computes what transform caches are needed for source attributes.
If an attribute is in both source and target_attrib_info/target_group_info, it will be taken from target if myCombineMethod is COPY, and will be taken from source if MULTIPLY, ADD, or SUBTRACT.
If there is only a source, e.g. if output_geo is the internal detail of a packed geometry primitive, omit target, target_attrib_info, target_group_info, and num_target_attribs.
If there is only a target, pass nullptr for source, and then num_source_attribs, has_transform_matrices, and needed_transforms will be ignored.
NOTE: num_source_attribs or num_target_attribs, if non-null, should be an array long enough to support GA_ATTRIB_VERTEX, GA_ATTRIB_POINT, and GA_ATTRIB_PRIMITIVE as indices, (3 at the moment, since they come first in GA_AttributeOwner). NOTE: needed_transforms, if non-null, should be an array of length NeededTransforms::num_needed_transforms.

Uses the transforms in cache and geometry from source to create num_packed_prims packed geometry primitives referencing the same geometry. If the source groups are null, source_handle will be used to create the packed geometry primitives.
If target and the later parameters are non-null, target attributes in target_attrib_info and target_group_info will be copied from the points in target_point_list.
NOTE: This will clear output_geo if the topology has changed since the previous cook.

This sets the packed primitive local transforms, sets P based on the translations and pivots, (i.e. it first calls GUupdatePackedPrimTransforms), then removes unnecessary attributes, adds needed attributes from target, and copies target attribute values.
NOTE: constant_pivot being null means to get pivots from the primitives.
