`bringToFront` DevTools message is sent when breakpoint is triggered
or inspect is called and Chromium upon this message activates DevTools
via `DevToolsUIBindings::Delegate::ActivateWindow`:
```
void DevToolsWindow::ActivateWindow() {
  if (life_stage_ != kLoadCompleted)
    return;
\#if BUILDFLAG(IS_ANDROID)
  NOTIMPLEMENTED();
\#else
  if (is_docked_ && GetInspectedBrowserWindow())
    main_web_contents_->Focus();
  else if (!is_docked_ && browser_ && !browser_->window()->IsActive())
    browser_->window()->Activate();
\#endif
}
```
which implements: `DevToolsUIBindings::Delegate::ActivateWindow`.

Electron also implements this interface in:
`electron::InspectableWebContents`. However it was only setting
a zoom level, therefore this commit extends it with activation
of the DevTools.

Only supported for DevTools manged by `electron::InspectableWebContents`.

Closes: #37388
