[core] Store SegmentVectors in ephemeral render objects

We used some shared SegmentVectors, e.g. for drawing raster or background tiles.
In longer running maps, this lead to resource accumulation. By storing the SegmentVectors
and the contained gfx::DrawScope objects, we ensure that resources get released
when the associated render objects vanish.
