Sculpt: Cloth Brush Soft Body Influence property

This property adds constraints to the simulation using the initial
location of the vertices, making it behave like a soft body. The
strength of these constraints can be modified with the brush parameter.
This makes some deformation modes more subtle and predictable, making it
possible to use the cloth brush to add surface detail in a more
controllable way without loosing completely the original shape of the
mesh.

Fix T78285: Invalid thread safety in shrinkwrap modifier code.

This uses mesh's runtime mutex for both `BKE_mesh_runtime_looptri_ensure`
(was using its own global RW mutex before), and `BKE_mesh_wrapper_ensure_mdata`
(was not protected at all before).

This is more like a band-aid than a proper fix, as mentioned in the report
proper fix would be for the modifier to request those data (the relevant
BVHTree, which would implicitely also call the tow others) through flags,
just like it does for regular CDData layers. But this is a much bigger
refactor to be done outside of bugfix scope.

Fix Cloth Brush global Sculpt gravity applied in the wrong falloff

Previously, gravity was only applied in the real brush radius, not in
the whole simulation radius. For most deformation modes, applying
gravity to the entire simulation instead of just to the brush radius and
scaled by the radius (like a regular sculpt brush) makes more sense.
After this fix and with the cloth collisions patch applied, it is possible
to do things like this with the cloth grab brush.

Fix T79054: Crash with Cloth Brush and anchored stroke

As the comment says, anchored stroke can't rely on the first stroke
iteration for creating the simulation data. Probably lost in a cleanup.

I also made that anchored stroke doesn't restore the mesh state in the
cloth brush, so it can create the simulation effect.

Compositor: Fix node preview when input resolution is not known

The final render will use scene resolution in this case.

For example, when Color Input is plugger to preview and composite output
nodes, final render will flood-fill the final image which is a size of
scene resolution with this color. Before this fix the node preview was
empty. After this fix the node preview will be flood-filled with the
color.

Compositor: Fix calculation of preview resolution

Were two issues:

- Divider was calculated in integer domain, causing rounding issues in
general case, and causing singularity in a corner case when input is
smaller than the preview size.

- The resolution was scaled down by 1 pixel for no obvious reason.

LineArt: Remove RenderTriangle::gc. This variable was never really used.
