Fix #31350, by Sergey Sharybin.

This happens because of how output node index is initializing in assign_index function: itterator goes to the beginning of the nodes list using node->prev and then reviews the whole node list to find first unused index. The problem is that node's initialization now is getting called before node was added to node tree, so all output nodes have got equal index.

Fix #31363. Group interface sockets don't have a parent node, so the API function has to check that before making the update call.

optimize ngon angle calculation in solidify modifier (was doing prev/next vector subtract and normalize for every vertex). now store the previous normalized vector for re-use.

also add BKE_mesh_poly_calc_angles() which is mostly a reference for now.
