[core] Handle zero text size
The style specification stipulates that `text-size` values must be positive
(https://docs.mapbox.com/mapbox-gl-js/style-spec/#layout-symbol-text-size).
However, a zero value could be passed to the engine (e.g. as a result of
an expression) this patch handles it and avoids assertion hit in `shaping.cpp`.
