3b6ee8cee7 Refactor: Move vertex group names to object data
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.

As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to an object.

The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.

This patch leaves the object-level python API for vertex groups in
place. Creating a geometry-level RNA API can be a separate step;
the changes in this commit are invasive enough as it is.

Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.

72e741ee62 Fix T80897: Complex solidify crash when special ngons are merged
This has serious performance implications as the additional check makes
it O(N^2) when there are a lot of merged vertices.
The goal is to move the merging to the weld modifier where it would
be much easier to optimize.

6414da0381 Cleanup: enable and silence Clang-Tidy readability-function-size
Enable Clang-Tidy's `readability-function-size` rule and add a few
`NOLINT` markers to explicitly silence warnings for three functions.
These functions are huge and would IMO benefit from splitting up, but
are hard to without intimate knowledge of the code.

At least by enabling the rule, we can start tweaking the values and
refactoring other functions that bubble up as being too long/complex.

No functional changes.

b2d850efc0 Cleanup: Solidify modifier: Remove unneccessary error message.
For any modifier, the expected output when the input mesh is empty, is an
empty mesh. So this error message was useless, and could spam the
console in some usecases of the modifier stack...

cc9bee9162 Add Complex Solidify option for thickness per face
Add an option to solidify complex which will make faces which have thickness
controlled by vertex weights flat/even, and parallel to their original face.

For each face it uses the minimal weight assigned to its vertices to control
the thickness.

This will help users for example in architecture or basic CAD design by finally
making solidify work there at all if altering thickness is needed.

35b1cc806f Improve Solidify/Bevel Modifier cooperation
Adds a slider to solidify which allows the user to add bevel weight on the outside
or remove bevel weight from the inside.

Also includes a very small improvment for working with subsurface modifier where
the rim edge in complex solidify will now also have a chance to get a crease if
there is only two adjacent edges.

5cf7283342 Fix T75032: New complex solidify algorithm handles poorly merging threshold of small geometry details.
* Implemented the algortihm that would merge vertices to the weighted
  center between them.
* Exposed the merge threshold to the user.

The new default tolerance is 0.0001 (versionning code ensures that
previous default value remains in use to avoid any change in existing
files).

bd86edf116 Solidify modifier: add option to assign shell & rim geometry to selected vertex groups.
This commit gives the solidify modifier the ability to assign the newly created shell
and rim geometries to selected vertex groups. This expands the procedural control over
the modifier stack by letting users apply modifiers to the shell geometry without affecting
the original geometry.

This will be especially helpful for NPR users that use solidify to create backface
culling lines on their characters giving them the ability to add displace noise
and other effects.

bb19d96bc5 Fix solidify complex degenerate cases with duplicate faces

241248223a Change solidify's material offset in complex mode to conform with simple mode
this patch will change the behaviour of the material offset in complex mode to fit simple mode output.
Previously in complex mode this would offset the material of the enire shell,
because when you read the tooltip it says material for new generated geometry.
In complex mode everything is new generated geometry though.
In simple mode on the other hand, this would give you a way to only change the inside faces
material. There may be cases in large modifier stacks where material offset like it is implemented
currently in complex mode may be useful, but it is much more useful in the way it is implemented
by simple mode.

e45cfb574e Solidify Modifier: support non-manifold input
This adds a new mode to solidify to support non-manifold geometry
with edges using 3 or more faces as input, resulting in a manifold mesh.

Since the differences between these methods don't translate well
into short terms, they're named "Simple" and "Complex" in the UI.

This also adds clamp with respect to angles
to the existing solidify modifier calculation.
