The main motivation for this is that it's part of a fix for #113377,
where I want to propagate the edit mesh pointers through copied
meshes in modifiers and geometry nodes, instead of just setting the
edit mesh pointer at the end of the modifier stack. That would have
two main benefits:
1. We avoid the need to write to the evaluated mesh, after evaluation
which means it can be shared directly among evaluated objects.
2. When an object's mesh is completely replaced by the mesh from another
object during evaluation (with the object info node), the final edit
mesh pointer will not be "wrong", allowing us to skip index-mapped
GPU data extraction.
Beyond that, using a shared pointer just makes things more automatic.
Handling of edit mesh data is already complicated enough, this way some
of the worry and complexity can be handled by RAII.
One thing to keep in mind is that the edit mesh's BMesh is still freed
manually with `EDBM_mesh_free_data` when leaving edit mode. I figured
that was a more conservative approach for now. Maybe eventually that
could be handled automatically with RAII too.

The selection engine renders `uint` texture where each element of the
geometry is represented as an index.
When the geometry have modifiers, the original index was used for the
texture.
However this is not necessary for the select engine to work. The real
mesh indexes can be used in the texture and, only at the end, the
original index can be retrieved on the CPU itself.
Advantages of this approach:
- Optimizes the code to generate selection buffers.
- Makes the select id texture more informative as it identifies the
real elements instead of the original ones.

The previous algorithm for interpolating the vertices of an edge using
a lambda in screen space was heavily dependent on the resolution of the
projection matrix, leading to precision loss when the clip distance
range was high.
The updated algorithm now adjusts the lambda according to the
perspective before performing the interpolation, which improves
precision regardless of the clip distance range.
Caused by 7ed02da2be.
`curr.ob_index` is -1 when the ray does not hit any face
(`knife_find_closest_face`). This will lead to crash when mouse
is not over any faces. To avoid crash, use `bvh.ob_index`.

A couple of edit mesh operators are still using "VCols" terminology,
which should be Color Attributes now. This just renames text seen
in redo panels. Internally it's still called VCols.

Also access the evaluated deform mesh with a function rather than
directly from object runtime data. The goal is to make it easier to use
implicit sharing for these meshes and to improve overall const
correctness.
Move the public functions from the editors/object (`ED_object.hh`)
header to the `blender::ed::object` namespace, and move all of the
implementation files to the namespace too. This provides better code
completion, makes it easier to use other C++ code, removes unnecessary
redundancy and verbosity from local uses of public functions, and more
cleanly separates different modules.
See the diff in `ED_object.hh` for the main renaming changes.

Also fix the poll to properly check for the remaining unsupported types.
Don't add back Quaternion support, since that's arguably less useful,
and we might want different ways to set those values compared to
just entering WXYZ.
Most likely caused by 6d491da0be
In that commit, `knife_pos_data_clear` started to clear (set `-1`) the
value of the current object (which is expected).
However, `knife_snap_angle_relative` relies on the current object to
transform the face normal to global space.
This is weak and error prone since the face is obtained from the
function itself.
The code could be optimized and reuse the face identified in
`knife_snap_curr`, but for now just identify the face object.
Fix the "Merge Vertices" report, replacing "vertice(s)" with either
"vertex" or "vertices". The singular "vertice" is not a word in English,
and thus the regular "append (s)" approach is incorrect.

Now that all relevant code is C++, the indirection from the C struct
`GPUVertBuf` to the C++ `blender::gpu::VertBuf` class just adds
complexity and necessitates a wrapper API, making more cleanups like
use of RAII or other C++ types more difficult.
This commit replaces the C wrapper structs with direct use of the
vertex and index buffer base classes. In C++ we can choose which parts
of a class are private, so we don't risk exposing too many
implementation details here.

Replace the use of the `LIB_TAG_DOIT` flag which cwas used to
only process each object data ID once with a Set. Return the objects
or bases in a Vector. Now we only iterate over the view layers bases
once instead of three times.

Converting a color attribute to a non-color domain or type causes vertex
paint mode to try to change the attribute even though it's unsupported.
That leads to a crash here and unpredictable behavior elsewhere.
This PR modifies some poll functions to check for the proper domain and
data type before continuing. Even if converting an attribute properly
updates the active color attribute, we can still run into situations where
the active name references an attribute with incorrect metadata.

Fix for a crash after undo "Mask slice to new object"
When creating a new mesh object in the mask slice operator in
sculpt mode it caused a crash when undo to the initial undo step.
Moreover saving the sculpt undo state seems not necessary in
this function since undo/redo doesn't really work reliably for this
operator from the start, but there is nothing can be done about it
without systemic changes.
Note: this PR replaces #119401

This could happen if objects were hidden after going to editmode and
knife was used on them.
In that case, raycasting would (rightfully) fail, but there is a
fallback in place using the back-buffer selection method (in which the
hidden object is still present). So a face would be found, but this
makes all following code confusing/wrong since we are working with
coordinates / faces under the assumption there would be a valid/
corresponding object to it in `KnifeTool_OpData` > `objects` -- which is
not the case...
So to resolve, just check if the object is visible before calling
`EDBM_face_find_nearest` in knife code.
Alternativeliy, we could also add a check for Base viewport visibility
to all the bmesh `find_nearest` functions (a bit hesitant though since i
am not sure this would be desired in all cases)

I think the issue is that the run-node-group operator overwrites the data stored in the
`Mesh` while mesh edit mode operations typically only change the `BMEditMesh`. It
seems like that causes issues because the mesh edit mode undo stack does not
keep track of changes to the `Mesh`. When hitting undo, Blender assumes that the
`Mesh` stored in the object has not changed and therefore it does not have to be
read from the undo step again.
The preliminary fix implemented here is to just not change the `Mesh` but only the
`BMEditMesh` like any other edit mode operator. This seems to solve the issue.
I haven't quite figured out yet how to tell the undo system that the `Mesh` has to be
loaded from the undo step when undoing out of mesh edit mode. Doing that might
provide a better solution.

"Own" (the adjective) cannot be used on its own. It should be combined
with something like "its own", "our own", "her own", or "the object's own".
It also isn't used separately to mean something like "separate".
Also, "its own" is correct instead of "it's own" which is a misues of the verb.
- Remove unused members.
- Use C++ vector types.
- Rename variables.
- Avoid redundant calls.
- Pass the modified value as a function return parameter.
Caused by 1c0f374ec3
When `EDBM_edge_find_nearest_ex` does not find a nearest edge in
`loopcut_mouse_move`, then `loopcut_update_edge` will set
`RingSelOpData` `ob` to nullptr (rightfully so).
This would then crash in `ringsel_draw` (because we are trying to call
`object_to_world()` on the nullptr).
Prior to 1c0f374ec3 this was also "wrong", but
`EDBM_preselect_edgering_draw` would early out before using garbage
data.
Now guard against this and dont call `EDBM_preselect_edgering_draw` at
all if we dont have valid input.
