panfrost: Implement pan_tiler for non-hierarchy GPUs

The algorithm is as described. Nothing fancy here, just need to add some
new code paths depending on which model we're running on.

Tomeu:
- Also disable tiling when !hierarchy and !vertex_count
- Avoid creating polygon lists smaller than the minimum when
  vertex_count > 0 but tile size smaller than 16 byte
- Take into account tile size when calculating polygon list size for
  !hierarchy
- Allow 0-sized tiles in a single dimension
