With both text (curses) and graphics (vnc/sdl/spice/...) display active vga text mode emulation fails to update both correctly. Depending on whenever vga_update_text() or vga_draw_text() happens to be called first only the text display or only the graphics display will see display resolution changes and full redraws.
Fix it by calling both text/gfx resize functions in both code paths and keep track of full screen redraws needed in VGACommonState fields.
