* Webview API prototype 3 Part of #43713 Third try at refining the webview api. This pass reworks #44165. Major changes: - Adds an `id` field to webviews. The id is provided by the extension and identifies the webview. It is used with the new event handling apis. - Adds a new `onDidChangeActiveEditor` api. This is similar to `onDidChangeActiveTextEditor` but is also fired when you change webviews. It replaces the old `onFocus` and `onBlur` events on the webview itself - Adds an `onDispose` event ot webviews. This is fired when a webview is closed by the user - Perist webview state when the editor group changes. This is enabled for all webviews, not just those with keep alive. * Throw error when trying to access disposed webview * Improving webview documentation * Clean up dispose management * Throw if we receive a bad handle * Move more event handling to input * Simplify input updating * Remove extra container property * Fixing md security alert button * Remove extra update container call * Restore syncing of preview to active editor * Fixing posting to webview * Debounce preview updates * Remove previewUri * Enable direct window.postMessage instead of window.parent.postMessage * Fixing scroll position not preserved when updating previews * Revert parent.postMessage change. Old behavior was correct * Properly hide webview container on tab switch * Make sure we only handle scroll events for the correct document * Don't try setting negative scroll * Revert vs code whitespace change
