Rename Instances<T> to Table<T> and the "instance" terminology to "TableRow" and "element" (#2981)

* Instances -> Table

* instances.rs -> table.rs

* Rename occurrances of the word "instances"

* .instance -> .element

* Instance* -> TableRow*

* Rename Table and TableRow methods to not say "instance"

* Remove presumed unused serde defaults now that tables default to length 0 not 1

* Rename occurences of the word "instance"

* Un-alias the RasterDataTable<Storage>, VectorDataTable, GraphicGroupTable, ArtboardGroupTable typedefs

* Move artboard type and node code out of graphic_element.rs to a new artboard.rs

* Organize the TaggedValues

* Fix tests

* Fix prior regression with Image Value node not upgrading
