PreloadingDevTools: Disable prerendering for clients other than DevTools frontend

Prerendering introduced switching of FrameTreeNodes in the browser side
and frame targets in the CDP client side. If a CDP client unaware of
this logic and a prerendered page activated, it will cause unexpected
behaviors. For example, Puppeteer loses control. To mitigate this, this
CL disables prerendering if a target without tab target support is
attached. For more details, see [1].
