This should fix most of the shrinkwrap artifacts when the preserve volume option is active. After this commit the default voxel remehser settings should not fail in the default cube.

Quadriflow does not support non manifold meshes. (Edges with > 3
connected faces and discontinuous face normal directions)
While it does sometimes "work" in these configurations, the results are
not good and in most cases it just flat out will crash.
Added a sanity check to make sure that the input mesh is manifold.

This commit enables OpenVDB adaptivity in the voxel remesher. It can be useful to reduce the polygon count if you want to switch to dyntopo after using the voxel remesher workflow.

This patch adds paint symmetry support to Quadriflow. It bisects and mirrors the input and the output from the remesher to build the final mesh using the preserve boundary option.
This is also an important performance improvement in Quadriflow because it only needs to process half of the mesh with half the resolution.

This commit fixes most of the issues we currently have in the voxel remesher. Mesh volume is preserved when doing multiple iterations, so the sculpt won't shrink and smooth each time you run the remesher. Mesh topology is much better, fixing most issues related to mask extraction and other topology based operations.

This commit also removes the name "voxel" from the messages because this function
is now used for the voxel remesher and quadriflow.

The active object can be `NULL`, which causes a segfault in
`BKE_object_is_in_editmode(NULL)` (and if that were made NULL-safe, the
segfault would happen further down in `object_remesh_poll()`).
These functions deal with voxel remeshing of Mesh data,
and aren't related to MOD_remesh.c for e.g.
Name so other kinds of remeshing wont cause confusion.
The voxel remesher introduces a new workflow for sculpting without any of the limitations of Dyntopo (no geometry errors or performance penalty when blocking shapes). It is also useful for simulations and 3D printing.
This commit includes:
- Voxel remesh operator, voxel size mesh property and general remesh flags.
- Paint mask reprojection.
- Geometry undo/redo for sculpt mode. This should support remesh operations as well as future tools that modify the topology of the sculpt in a single step, like trimming tools or mesh insert brushes.
- UI changes in the sculpt topbar and the mesh properties pannel.
