Initialize high dpi early in the chrome process on Windows by calling the SetProcessDpiAware API in chrome.exe instead of chrome.dll

This API needs to be invoked as early as possible in the process. Not doing this causes the OS to assume that the process
needs dpi scaling which leads to bad things. We also need to initialize high dpi in the gpu process as it is involved in win32
operations like painting, etc.
