Use keyboard-types crate
Have embedders send DOM keys to servo and use a strongly typed KeyboardEvent from the W3C UI Events spec. All keyboard handling now uses the new types. Introduce a ShortcutMatcher to recognize key bindings. Shortcuts are now recognized in a uniform way. Updated the winit port. Updated webdriver integration. part of #20331
