Auto-generate enum type widget boilerplate for radio buttons and dropdown menus (#2589)

* First draft of factoring out the dropdown boilerplate

* Add proc macro for enum boilerplate

* Detect whether to say `crate` or the name

* Clean up the input and naming of the enum macro

* Rename a file

* Do the rename of code too

* Use the attribute-driven selection of radio vs dropdown

* Add a metadata struct and tooltips

* Move the new traits to a better place.

* Use ChoiceType, part 1

* Use ChoiceType, part 2

* Introduce a builder API for choice widgets

* Start using the new new API

* DomainWarpType should be a dropdown still

* Handle the case where a node property can never have a socket

* Rustfmt

* Code review

* Update stable node IDs in test
