Fluid: Use OpenVDB as the default cache format for liquids too

With the updated OpenVDB setup, it is now perfectly fine to use OpenVDB for liquid domains.

UI: Add Free Handle Types to CurveProfile Widget

Under the hood the CurveProfile widget (used for bevel custom profiles)
uses a bezier curve, but right now though it only supports two of the
bezier curve handle types, vector and auto. This patch adds support for
free handles and adds all of the logic for editing them.

This is the first step to the ability to import and export curve objects
in the widget.

There's some code cleanup in curveprofile.c. Movement for handles and
control points is abstracted to functions there rather than happening
in interface_handlers.c.

An "Apply Preset" button is also added, which solves a confusing issue
where you apply a preset, then change the number of samples and the
preset doesn't change. The button makes it clear that the preset needs
to be reapplied.

Fix T67319 DRW: Large objects gets incorrectly culled

To avoid this we just bypass culling if the object is too big to avoid
float precision issues.

Fix artifact in Clay Strips when producing large deformations

The clay strips brush tip tests distances against a cube with beveled Z
aligned edges. This cube was positioned with its center in the surface
of the mesh, so when producing large deformation, some vertices that
should be deformed were positioned further than the cube's Z dimension,
so they were left behind, producing artifacts.
This displaces and deforms the local space to position the brush tip
cube (now a prism) towards the deformation direction, so more vertices
can be included, removing most of these artifacts.

Fix T78188: Sculpt mask glitching after using sculpt vertex colors

Fluid: Improved OpenVDB support for fluid caches

This commit makes uses of the new OpenVDB IO in Mantaflow (introduced in 781f783a66ac).

From now on, fluid cache files in OpenVDB format will contain a list of grids per frame (before: one .vdb file per grid per frame). Besides regular grids, particle systems are also stored using OpenVDBs PointGrid data structures.

All older cache formats will remain fully functional:
- Uni caches (.uni) files are still available from the UI and can be used as before
- Raw caches (.raw) are no longer available from the UI, but loading them is still possible
- Old OpenVDB caches (one .vdb per grid) can no longer be baked either, but loading them is still possible.

It is also no longer possible to choose file formats for 'Noise' and 'Particles'. Instead there are now options to set the file format for 'Volumetric' and for 'Mesh' data.

Known issues (planned to be resolved soon):
- OpenVDB files are currently not taking into consideration the clipping value (FluidDomainSettings). Empty cells are therefore being written too. Depending on the scene, this can make file sizes unnecessarily large.
- Domains are not being exported at their world position. Instead they are always clipped to the origin.

Fluid: Updated Mantaflow source with latest OpenVDB changes

This updated set of Mantaflow files includes the improved OpenVDB file IO. With this update it is finally possible to store multiple grids per file. It is also possible to save particle systems and particle data to OpenVDB files.
