Fix usage of SDF on VoxelTerrain

It causes the blocky mesher to be called potentially with uniform blocks,
which is actually a valid case to handle better in the future.

Fix rare bug with vertex sharing causing long spiky artifacts
...
Basically we were checking case code of the ReuseCell to know if we can
re-use a vertex from it, but sometimes the associated cell did not write
a re-usable vertex, and we were not resetting such vertex indices.
So in some cases, we were accessing a very old index.
The case code doesn't need to be remembered, we just reset the first vertex.
No need to check if the ReuseCell was empty, we can read the vertex directly,
as it will be -1 anyways if it isn't re-usable. At least, this fixed the bug
and did not reproduce after testing a lot of noise data sets.

Transition meshes WIP and bug fixes

Work remains to be done:
- Transform the mesh into proper orientation
- Introduce secondary positions to make it fit in a regular block
- Make it available in the API and use it in terrain nodes

Forked Transvoxel mesher into an MC one with overlap seam mode.
...
It's mostly because the transvoxel mesher is going to change,
and the MC mesher will only act as a simplified legacy mesher.
It has experimental support for overlap seams, but it didn't work
well due to Z-buffer precision being too weak.
