Codechange: [OSX] Use more exact enum names where introduced with the 10.12 SDK.

The enum values still have the exact same numerical values, but the 10.12
SDK introduced more explicit names (e.g. like NSEventTypeApplicationDefined
instead of NSApplicationDefined) for several enum constants.
Use them when available.
