Geometry Nodes: improve multi socket handling in evaluator

Previously, the values passed to a multi-input socket were stored
in the order that they arrived in. Then, when the values are accessed,
they are sorted depending on the link order.

Now, the ordering is determined in the beginning before execution starts.
Every value is assigned to the right index directly, avoiding the sort
in the end. This makes the ordering more explicit.
