Rewrite w32fns.c's `x_set_menu_bar_lines'

* src/w32fns.c (x_set_menu_bar_lines): Redraw frame immediately
regardless of whether menu bar is added or removed.  Clear
under internal border iff a W32 window exists.  Store either 0
or 1 as new parameter value.
(x_change_tool_bar_height): Use FRAME_W32_WINDOW instead of
FRAME_X_WINDOW.
