Adapt win32 theme calls to use dpi dependent variants

[akoch-yatta]

There is already an old branch, that should be doing most of it. But it needs to be retested. https://github.com/akoch-yatta/eclipse.platform.swt/tree/use-dpi-dependent-win32-api-calls

One old issue was positioning of text in the menu items in the menu bar. If the menu bar is not on the primary monitor they will either be too high to or too low´. One proabable solution could be:

1. Do not forward text to the OS in this case in MenuItem::setText
2. Draw the text directly via the GC similar to the drawing of the image in MenuItem::wmDrawChild
   You can check whether the parent Menu has custom drawing enable with Menu::needsMenuCallback

Master does now contain the neccessary win32 API calls, so I rebased the branch mentioned above onto master.
