NEWT Screen: Allow injection of global (single) monitor size in [mm] via newt.ws.mmwidth and newt.ws.mmheight property

This is essential on bare-metal devices where the screen DRM/GBM driver does not provide the screen-size (in mm).
Otherwise we would have resolution/(size_mm=0) infinity density and none of our graph font demos would work,
as we compute pixel-em-size based using dpi and pixel-pt-size.
