The curses concept of a window has been supported but never actively used in iPXE since the mucurses library was first implemented in 2006. Simplify the code by removing the ability to place a widget set in a specified window, and instead use the standard screen for all drawing operations. This simplification allows the widget set parameter to be omitted for the draw_widget() and edit_widget() operations, since the only reason for its inclusion was to provide access to the specified window.
