Antoine Leblanc a978b6d683 Remove several outdated backend constraints ... ## Description This PR removes as many constraints as possible from Backend without refactoring the code. Thanks to #1844, a few ToJSON functions can be removed from the IR, and several constraints were simply redundant. This PR borrows from similar work done as part of #1666. ## Note To remove constraints more aggressively, I have explored the possibility of _removing Representable altogether_, in a [separate commit](https://github.com/hasura/graphql-engine-mono/compare/nicuveo/remove-extension-constraints..nicuveo/tentative-remove-representable). I am not convinced it's a good idea in terms of readability of the code, but it's a possibility. Further work includes deciding what we want to do with `Show` and `ToTxt`; see #1747. https://github.com/hasura/graphql-engine-mono/pull/1843 GitOrigin-RevId: 337324ad90cb8f86f06e1c5a36aa44bb414e195a		2021-07-27 13:52:20 +00:00
