* [Sema]: Add Codable synthesis for enums with associated values * Incorporate review feedback for enum Codable synthesis * Implement enum specific versions of existing Codable tests * Encode parameterless enum cases as * Add test for overloaded case identifiers * Align code generation with latest proposal revision * Put enum codable derivation behind flag * clang-format sources * Address review feedback and fix tests * Add diagnostic for conflicting parameter identifiers * Restructure code after rebase
