Fix for drawing check box in the wxPG edit mode when RTL layout direction is set under wxMSW.

Browse Source 
Check box isn't drawn correctly in the edit mode under wxMSW due to the problems with RTL handling in wxAutoBufferedPaintDC and wxPaintDC (see #16254).
We need to only draw the image, no text, so we can work around the problem by overriding layout direction to LTR.
