Handle emulated device scale factor and original device scale factor properly in use-zoom-for-dsf mode.
* The zoom level is set to the original device scale factor (m_compositorDeviceScaleFactorOverride).
* Sets the page's dsf to emulated dsf / original dsf so that device pixel ratio becomes emulated dsf.
* Explicitly call ScreenMetricsEmuation::Apply so that RenderWidget can tell if it's in emulation mode.
* Remove DevToolsHost.convertLengthForEmbedder because it's no longer necessary.
