fix[DevTools/Tree]: only scroll to item when panel is visible (#32018)
Stacked on https://github.com/facebook/react/pull/31968. See commit on top. Fixes an issue with bank tree view, when we are scrolling to an item while syncing user DOM selection. This should only have an effect on browser extension. Added events with `extension` prefix will only be emitted in browser extension implementation, for other implementations `useExtensionComponentsPanelVisibility` will return constant `true` value.
