Wire 'Inspect Element' action to the new DevTools (depending on the devtools flag):

- Add new devtools IPC message
- Expose WebView's hit target
- Refactor dom_agent interaction not to send information known to client
- Collect incoming messages on the client until frontend is loaded
- Add Inspect Element scenario into the devtools_host_stub
