Shifted a lot of pin adding functionality from Blueprint Details customizion to the nodes themselves or BlueprintEditorUtils.
#jira UE-11334 - Dragging a pin to a node that can add pins (function entry/exit, custom events...) should add a pin of the type to the node.

Reworked connection logic in the behavior tree graph schema.
Found that while the code to check while dragging/hovering was switched when dropping interms of pin direction. This made denying connections in directed graphs (like BTs) problematic. Fixed this by just reversing the pin order on drop, tested in Blueprint & it seems to be working fine.
Also fixed creating graph cycles, which caused a crash.

- Clean up FDragConnection construction and add a factory function in SGraphPin to extend it for some pins
- Clean up arguments to FOnGetContextMenuFor in SGraphPanel
- Various modifications to SGraphPin to permit implementation of wire knots/reroute nodes

#add Added UEdGraphNode::GetNodeNativeTitle to return a native title for a node.
#add Added UEdGraphNode::GetNodeSearchTitle to return the native and localized title for a node, together, for searching.
#add Can hold "alt" over a node (in the graph panel, or the palette) to see the native name of the node.
