protocol: clarify wl_surface.destroy with pending release callbacks

Browse source 
Since the client cannot destroy wl_callback objects itself, the
compositor must send wl_callback.done.

The callback_data passed in the wl_callback.done event is unused and
is always zero.
Sending this request without attaching a non-null buffer in the same
content update is a protocol error. The compositor will send the
no_buffer error in this case.
If the wl_surface is destroyed while it contains uncommitted release
callbacks, the wl_callback.done event is sent immediately.
If a content update is committed and contains release callbacks, it must
also contain a non-null buffer. Otherwise, the compositor sends the
no_buffer error.
