Fix copyright headers

Summary:
Update several files to use the proper copyright header:

```
//  Copyright (c) Facebook, Inc. and its affiliates.
//
// This source code is licensed under the MIT license found in the
// LICENSE file in the root directory of this source tree.
```

In the case of Xcode project files, I used the shortform version, `Copyright (c) Facebook, Inc. and its affiliates.`
