[Multilang] hardcode ABI into abi-gen-wrappers (#1883)

* Export artifacts and addresses from abi-gen-wrappers

* only export addresses, not artifacts

* abi-gen-wrappers no longer accept ContractAbi as constructor param

ABI is now hardcoded when wrapper is generated

* remove unused imports

* remove unused import

* changes after review

* fix method ordering

* update constructor args

* prettier

* statically enumerate ABI properties

* remove abi-gen-wrappers generated-wrappers from prettierignore
