wl_backend: forward pointer events to client surface in client area 

frame_buf_at() matches the entire window frame tree including the
client content area. This caused wl_update_pointer_focus to never
set seat pointer focus on the client surface, so Wayland clients
(like WPrefs) never received pointer enter/motion/button events.

Fix: when frame_buf_at returns a hit, also check view_surface_at.
If a client surface is found at the pointer position, use it instead
of treating the area as WM-internal decorations.
