The 'sun.java2d.dpiaware' property controlled whether Java tried to declare itself DPI Aware for Windows. Setting this property didn't work after dpiaware flag was added to the application manifest.

It doesn't work now because Java launchers are Per-Monitor v2 DPI Aware via the application manifest.

Thus, we need to make sure that when sun.java2d.dpiaware is set to true we have Java process DPI awareness set to Per-Monitor v2 DPI Aware to match what is the manifest file.
