Currently the default DPI Awareness is true/PM, this won't suite everyone.

• Add CefSharpSettings option to allow for a new command line arg to be appended

• Change default to PerMonitorV2???

• Both browser process and GPU process (Chrome doesn't appear to worry about render processes) must have a matching awareness.

• app.manifest setting takes priority over Cef.EnableHighDPISupport();

• Chrome defaults to PerMonitorV2, we currently use PerMonitor

UPDATE
Chromium now sets the DPI Awareness to PermonitorV2 by default. You can override this via app.manifest or via programmatic call. #4410
