Implement dynamic table attributes to generalize the graphic-specific Table type (#4050)

* Feature-gate serde derives behind cfg_attr in all runtime node graph type crates

* Refactor Table to move its hard-coded fields into an attributes field

* Encapsulate TableRow/TableRowRef/TableRowMut attribute fields behind accessor methods

* Remove TaggedValue::GraphicUnused

* Refactor Table<T> to use dynamic attributes instead fixed names

* Fix code review soundness concerns

* Add todo work

* Replace row-oriented Table<T> API with column-oriented access

* Fix attribute propagation bugs
