wl_unmap: force commit sibling toplevels to clear stale popup pixels 

When a topLevel popup is unmapped, wl_redisplay(view-parent) clears stale popup pixels from the parent backing. But for rootView (common parent), the commit at the end of wl_redisplay is a no-op because rootView has no WLClientToplevel. The cleared backing was never pushed to any surface. Fix: iterate parent child list and force-commit every topLevel sibling, pushing the cleared backing to their wl_buffers.
