类型为 never 时返回的类型
// When `T` is a NOT `any` or `never` (like `string`) => Returns `IfNotAnyOrNever` branch
type A = IfNotAnyOrNever<string, 'VALID', 'IS_ANY', 'IS_NEVER'>;
//=> 'VALID'
// When `T` is `any` => Returns `IfAny` branch
type B = IfNotAnyOrNever<any, 'VALID', 'IS_ANY', 'IS_NEVER'>;
//=> 'IS_ANY'
// When `T` is `never` => Returns `IfNever` branch
type C = IfNotAnyOrNever<never, 'VALID', 'IS_ANY', 'IS_NEVER'>;
//=> 'IS_NEVER'
An if-else-like type that resolves depending on whether the given type is
