[CONSOLE.CPL]: Fix the console window preview:

[CONSOLE.CPL]: Fix the console window preview:
- turn it into a custom control;
- supports dynamic preview area depending on the actual current monitor screen resolution;
  (note that on ReactOS, the WM_DISPLAYCHANGE is not correctly sent, see CORE-13212, therefore this functionality won't show up yet)
- supports correct rescaling of the console preview drawn in the preview area;
- supports dependence of the console preview with respect to the chosen font character dimensions.
The code is there, it may be a little bit improved in the future.
CORE-13196 #resolve

Other additions:
- Add a few space between the console preview text window border and the text sample;
- PaintText and PaintStaticControls do not need to return anything.
