windows: get current display size (#8916)

Browse source 
For the moment the windows port has a single display with hard-coded
values.

This first PR is just to at least fetch the **actual size of the current
display**. The idea
is using this code as a first template to start getting familar with the
code base
and prepare the work for enumerating all displays.
