Adds support for formatting NS_CLOSED_ENUM and CF_CLOSED_ENUM alongside NS_ENUM and CF_ENUM.

Summary:
Addresses the formatting of NS_CLOSED_ENUM and CF_CLOSED_ENUM, introduced in Swift 5.

Before:

```
typedef NS_CLOSED_ENUM(NSInteger, Foo){FooValueOne = 1, FooValueTwo,
                                       FooValueThree};
```

After:

```
typedef NS_CLOSED_ENUM(NSInteger, Foo) {
  FooValueOne = 1,
  FooValueTwo,
  FooValueThree
};
```
