[PATCH] protocol: allow to send a zero physical output size

Physical size doesn't always make sense for all outputs. In case
it's not available or not relevant, allow compositors to send zero.

In practice this doesn't seem to break any client toolkit. We've been
doing that for a long time in wlroots.
