Remove fringe background extension code on W32.

* w32term.h (struct scroll_bar): Remove member `fringe_extended_p'.

* w32term.c (w32_draw_fringe_bitmap, x_scroll_run): Remove code for
fringe background extension.
(x_scroll_bar_create): Remove variables `sb_left' and `sb_width',
because they are now always the same as `left' and `width',
respectively.  Remove code for the case that `width' and
`sb_width' are different.
