Removed DARTIUM codegen for IDLS (sdk/lib/dartium)

tools/dom/src/dartium_KeyEvent.dart

-/**
- * A custom KeyboardEvent that attempts to eliminate cross-browser
- * inconsistencies, and also provide both keyCode and charCode information
- * for all key events (when such information can be determined).
- *
- * KeyEvent tries to provide a higher level, more polished keyboard event
- * information on top of the "raw" [KeyboardEvent].
- *
- * The mechanics of using KeyEvents is a little different from the underlying
- * [KeyboardEvent]. To use KeyEvents, you need to create a stream and then add
- * KeyEvents to the stream, rather than using the [EventTarget.dispatchEvent].
- * Here's an example usage:
- *
- *     // Initialize a stream for the KeyEvents:
- *     var stream = KeyEvent.keyPressEvent.forTarget(document.body);
- *     // Start listening to the stream of KeyEvents.
- *     stream.listen((keyEvent) =>
- *         window.console.log('KeyPress event detected ${keyEvent.charCode}'));
- *     ...
- *     // Add a new KeyEvent of someone pressing the 'A' key to the stream so
- *     // listeners can know a KeyEvent happened.
- *     stream.add(new KeyEvent('keypress', keyCode: 65, charCode: 97));
- *
- * This class is very much a work in progress, and we'd love to get information
- * on how we can make this class work with as many international keyboards as
- * possible. Bugs welcome!
