Add a `ClipboardDelegate` to the `WebView` API and a default implementation in libservo for this delegate that works on Mac, Windows, and Linux. Support for Android will be added in the future. This means that embedders do not need to do anything special to get clipboard support, but can choose to override it or implement it for other platforms. In addition, this adds support for handling fetches of clipboard contents and renames things to reflect that eventually other types of clipboard content will be supported. Part of this is removing the string argument from the `ClipboardEventType::Paste` enum because script will need to get other types of content from the clipboard than just a string. It now talks to the embedder to get this information directly. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
