language/primary_constructors/header/enum_declaring_parameter_error_test is added exercise this. language/primary_constructors/syntax/header_syntax_test and language/primary_constructors/syntax/final_formal_parameter_error_test are updated to not use 'var' modifier for enum declaring parameters. A message is added to the CFE to avoid referring to the implicit const enum primary constructor as "marked as 'const'".
