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.

Remove DNA headers, using forward declarations where possible.
Also removed duplicate header, header including it's self
and unnecessary inclusion of libc system headers from BKE header.
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.

This commit to complex solidify swaps the side of the geometry which
is affected by the material offset when the normal flip option is
enabled. This matches simple solidify and is considered correct/useful.

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.
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...

There is no user visible difference in standard builds, as there are no
volume modifiers yet. When using WITH_NEW_OBJECT_TYPES some deform only
modifiers are now available for hair and pointcloud objects.

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.

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.

* 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).
Review and minor changes/cleanups from Bastien Montagne (@mont29).
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.

The removal of duplicate faces that are created during the handling of
degenerate cases was implemented already but didn't work.
This patch should fix some crashes with the solidify complex mode
related to that.
See D7221 for details.
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.

- Use 'BKE_object_defgroup' prefix for object functions.
- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.
Sometimes on flat open vertices the thickness would suddenly start
to be jumping in powers of 2, also when bending a plane there is a
noticeable jump in the geometry.
When offset is set to -1 or 1 weird glitches happen.
See D6559 for test cases that failed.
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.
