Fix T93066: Alembic export ignores Mantaflow particles

`ABCPointsWriter::is_supported` already checked for valid particle
system types (liquid, spray, foam, bubbles, ...).

`AbstractHierarchyIterator::make_writers_particle_systems` did not
create a writer for these though, so now bring these in line and also
create writers for these.
