This enables HiDPI support for GTK+ on Windows, so that the fonts and window look better on HiDPI displays. Notes for the current work: -The DPI awareness enabling can be disabled if and only if an application manifest is not embedded in the app to enable DPI awareness AND a user compatibility setting is not set to limit DPI awareness for the app, via the envvar GDK_WIN32_DISABLE_HIDPI. The app manifest/user setting for DPI awareness will always win against the envvar, and so the HiDPI items will be always setup in such scenarios, unless DPI awareness is disabled. -Both automatic detection for the scaling factor and setting the scale factor using the GDK_SCALE envvar are supported, where the envvar takes precedence, which will therefore disable automatic scaling when resolution changes. -I am unable to test the wintab items because I don't have such devices around. https://bugzilla.gnome.org/show_bug.cgi?id=768081
