Update Chrome build instructions for Windows

The build instructions for Windows used to say that the Windows 10
14393 SDK was required. However the 15063 SDK has since been fixed and
Chrome will now build with it if it is installed. This change updates
the instructions.

The new instructions also mention VS 2017 as an option.
