Replaced `coba_*` with `color_ramp_*` in the Python API for fluid.

Fix T79914: Grab active vertex using wrong coordinates

This was introduced in the first commit of the cloth brush. In order to
support the cloth brush deformations with subsurf modifiers, the sculpt
API was changed to return the deformed coordinates from the PBVH instead
of the mesh coordinates. When using grab active vertex and rendering the
original mesh wireframe it should render the undeformed mesh coordinates
when available.

Fix Boundary Brush not working with partially hidden meshes

Now when a mesh is partially hidden using Face Sets, the open boundary
the hidden geometry produces is also detected by the brush.

Fix T78225: Vertex Colors not showing in edit mode

This should be using the mesh_cd_ldata_get_from_mesh function in
order to get ldata from BMesh in edit mode.

Fix T77763: Wrong highlight of active grab vertex

The "Grab Active Vertex" in sculpt mode highlights the vertex and
the neighbor vertices. This was working wrong in the case when mesh
has multires modifier at sculpt level 0 and has shape keys.

The issue was caused by the wrong crazy space calculation, which was
ignoring subdivision level. This is an oversight from the initial
implementation: the modifier has no effect if the subdivision level
is 0.

Multires: Fix memory leak when multires is at level 0

There is no SubdivCCG created in this case, meaning ownership of the Subdiv
was not altered.

Fix T80561: Crash when multi-mesh editing UVs with proportional editing

Because of a `goto` we would free a variable before it was declared.
Declare it before the `goto` and `NULL`-check the value before freeing.
