Currently there is a "calc_face_normal" argument to mesh to bmesh
conversion, but vertex normals had always implicitly inherited whatever
dirty state the mesh input's vertex normals were in. Probably they were
most often assumed to not be dirty, but this was never really correct in
the general case.
Ever since the refactor to move vertex normals out of mesh vertices,
cfa53e0fbeed7178c7, the copying logic has been explicit: copy the
normals when they are not dirty. But it turns out that more control is
needed, and sometimes normals should be calculated for the resulting
BMesh.
This commit adds an option to the conversion to calculate vertex
normals, true by default. In almost all places except the decimate
and edge split modifiers, I just copied the value of the
"calc_face_normals" argument.

1. Now will remove lines if both adjacent faces are back face.
2. Added a check to respect material back face culling setting.
3. Changed label in the modifier to "Force Backface Culling" (which reflect more accurately with what the checkbox does).

This commit renames enums related the "Curve" object type and ID type
to add `_LEGACY` to the end. The idea is to make our aspirations clearer
in the code and to avoid ambiguities between `CURVE` and `CURVES`.
Ref T95355
To summarize for the record, the plans are:
- In the short/medium term, replace the `Curve` object data type with
`Curves`
- In the longer term (no immediate plans), use a proper data block for
3D text and surfaces.

Some curve objects don't have an evaluated mesh at all, but line art
currently assumes that all curve objects have one before converting
it to a mesh internally. Fix this by checking if the curve object has an
evaluated mesh before skipping it.
The remaining problem is that evalauted from non-mesh objects or
evaluated curves from non-curve objects, etc. will be ignored if
"Allow Duplicates" is off. That's a different problem though.

When enabled, it will keep contour around the object instead of hide them by rule of face mark,
so the object can always have full contour while filtering out some of the feature lines inside certain regions.

Instead of splitting it at each occlusion change, it tolerates short segments of "zig-zag" occlusion incoherence and doesn't split the chain at these points, thus creating a much smoother result.

This option allows the edge to end right at the border
instead of extending beyond.
Useful when having multiple camera setup where you
want the border to be clean.
Also moved overscan option down inside "Composition" sub panel
