Eliminate bare Graphic and Artboard graph data by making Merge and Artboard nodes internally use tables

[Keavon]

• Remove the "To Element" node and replaces it with the "Wrap Graphic" node which produces table instead of singleton data
• Rename the "To Group" node to "To Graphic"
• Rename the "Flatten Group" node to "Flatten Graphic"
• Rename the "Layer" internal node to "Extend" and make it public-facing, while also removing its source_node_id setting functionality and making it work by concatenating two tables instead of pushing an element to a table
• Update the "Merge" node internals to avoid using singleton Graphic type data and use Table<Graphic> instead, like everywhere else
• Update the "Artboard" node internals to avoid using singleton Artboard type data and use Table<Artboard> instead, like everywhere else
• Rename the internal "To Artboard" node to "Create Artboard" and make it produce Table<Artboard> instead of singleton Artboard data
• Remove the "Append Artboard" internal node now that it can also use the new "Extend" node
• Create the "Source Node ID" node which breaks out the source_node_id setting functionality from the internal "Layer" and "Append Artboard" nodes to make it reusable
• Rename the "Unwrap" node to "Unwrap Option"
