Remove par nodes in favor of parbreaks 🔄

This basically reverts the earlier change from parbreaks to par nodes because:
- It is simpler and less nested
- It works way better with functions that layout their body inline like `font`, which where buggy before, previously

The original reasons for changing to par nodes were:
- the envisioned design of the layouter at that time (based on dynamic nodes etc.), which is not relevant anymore
- possibly existing benefits with regards to incremental compilation, which are unsure and outweighed by the immediate benefits of the parbreak-representation
