xlib binding, incorrect ChangeWindowAttributes

[SquishyBloob]

in vendor/x11/xlib/xlib_procs.odin
ChangeWindowAttributes :: proc(display: ^Display, window: Window, attr_mask: WindowAttributeMask, attr: XWindowAttributes)
should be
ChangeWindowAttributes :: proc(display: ^Display, window: Window, attr_mask: WindowAttributeMask, attr: ^XSetWindowAttributes)
to match the C function signature of
int XChangeWindowAttributes(Display *display, Window w, unsigned long valuemask, XSetWindowAttributes *attributes)
