plug-ins: improve a bit PDF export progression.

Subdivise progression steps inside layer groups.

It is not perfect yet as it would not handle perfectly weird edge cases
where you have for instance a lot of layers in a top layer group with
only many other top layers. But it would still handle it better than
before. Ideally we should simply count all non-group "leaf" layers in
the layer tree and use this as the number of steps. In other words, we
should do a first pass through the whole layer tree.
