toplevel-size: Report zero bounds as infinite

Browse Source 
Empty/zero bounds are sent by the Wayland compositor if there are no
valid bounds to report, e.g. if there are no connected monitors. Report
this to GTK, which uses this to clamp calculated sizes, as INT_MAX, so
that clamping isn't done until there are actual valid bounds to clamp
to.

This fixes clients sometimes shrinking to their minimum size during
hotplugs or after having suspended the session.
