We already have different storages for cddata of verts, edges etc.,
'simply' do the same for the mask flags we use all around Blender code
to request some data, or limit some operation to some layers, etc.
Reason we need this is that some cddata types (like Normals) are
actually shared between verts/polys/loops, and we don’t want to generate
clnors everytime we request vnors!
As a side note, this also does final fix to T59338, which was the
trigger for this patch (need to request computed loop normals for
another mesh than evaluated one).

This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
This is more like a band-aid than a real fix actually, real fix would be
to understand why rendering smoke requires auto texspace to be ON
(afaict, this was not the case in 2.7x)...
But I've already spent way too much time on this issue, at least now we
get better situation than before (i.e. smoke with adaptive domain works
well even when orig domain mesh has autospace flag disabled).
We should *never* prevent copying basic mesh CDLayers (vertices etc.),
that does not make sense.
I guess issue was not in old DM because geometry was duplicated anyway,
and in 'normal' modifier stack eval, probably because bare mesh was
awlays requested? But we should not have to be explicit here about it.
Passing depsgraph instead of scene, since a scene does not fully define the
state of object you want to use for the BVH.
Also, mesh_create_eval_final_view and mesh_create_eval_final_render are pretty
much the same, so mesh_create_eval_no_deform and
mesh_create_eval_no_deform_render are as well.

Since it seems that CD_ORIGINDEX is not available for loops,
the only choice is to simply use the loop normals already
computed by depsgraph after evaluating modifiers.
This revealed a bug where the Auto Smooth settings would be lost
from the mesh after complex modifiers, or after edit mesh to mesh
conversion, so restoring them is needed to get correct results.
Move all mask-related fields from Object and OperationDepsNode
to Object_Runtime and IDDepsNode. Auto-apply DEG_TAG_GEOMETRY
if the mask changes after DEG rebuild. Update DEG API and all
code that uses it.
This fixes "source mesh data is not ready" errors from Data
Transfer modifier when parameters are changed in the UI after
the recent mesh_get_eval_final fix.

Our mesh validation was only checking cd layout so far, not their actual
data. While this might only be needed for a few types, this is a
required addition for things like imported UVs, else we have no way to
avoid nasty things like NANs & co.
Note that more layer types may need that callback, time will say. For
now added it to some obvious missing cases...
It's a very bad idea to call this on non-COW instances - see T58150.
Also, when rebuilding mesh it's better to accumulate mask flags to
avoid possible repeated rebuilds from different users.
mesh_finalize_eval() may set ob->data to evaluated mesh, needs to be
done *after* call to BKE_mesh_texspace_copy_from_object(), else that one
is meaningless.
Related to investigations on T57985, but does not solve it at all. :(
The Nearest Surface Point shrink method, while fast, is neither
smooth nor continuous: as the source point moves, the projected
point can both stop and jump. This causes distortions in the
deformation of the shrinkwrap modifier, and the motion of an
animated object with a shrinkwrap constraint.
This patch implements a new mode, which, instead of using the simple
nearest point search, iteratively solves an equation for each triangle
to find a point which has its interpolated normal point to or from the
original vertex. Non-manifold boundary edges are treated as infinitely
thin cylinders that cast normals in all perpendicular directions.
Since this is useful for the constraint, and having multiple
objects with constraints targeting the same guide mesh is a quite
reasonable use case, rather than calculating the mesh boundary edge
data over and over again, it is precomputed and cached in the mesh.

- mesh_calc_modifiers & editbmesh_calc_modifiers
now follow similar naming.
- me and mesh were too easily confused in mesh_calc_modifiers
(remove 'me', access ob->data).
