Nodes: Remove unnecessary RNA pointer creation

`rna_NodeSocket_refine` and `rna_Node_refine` take significant time
when building the `NodeTreeRef` acceleration data structure, but they
aren't used at all. This commit removes their eager calculation and
instead creates them on-demand in the `rna()` functions. They also
aren't inlined to avoid including `RNA_prototypes.h` in the header.
