Bug 1672551 [wpt PR 26183] - webdriver: handle events with Unidentified key code, a=testonly

Automatic update from web-platform-tests
webdriver: handle events with Unidentified key code (#26183)

WebKit sets the event key code as Unidentified as per the spec (see
https://www.w3.org/TR/uievents-code/), but WebDriver tests expect an
empty string for the case of unidentified key codes. This patch changes
the code to an empty string when Unidentified is found.
