The C++ vertex group data accessor returned a span with null data that
wasn't empty. Instead of adding a null check as well as the size check,
just return an empty span when there is no vertex group data.
* Improve how the extend lines collision is calculated.
* Added `S` key to switch between modes.
* Now extend factor does not disable visual aids (thi sis done with checkbox).
* Reduce the use of linked list and now memory array is used.
* Refactor Radius functions.
* Fixed bug of Radius mode when object is rotated.
* Cleanup code.

Using the attribute name semantics from T97452, this patch moves the
selection status of mesh elements from the `SELECT` of vertices, and
edges, and the `ME_FACE_SEL` of faces to generic boolean attribute
Storing this data as generic attributes can significantly simplify and
improve code, as described in T95965.
The attributes are called `.select_vert`, `.select_edge`, and
`.select_poly`. The `.` prefix means they are "UI attributes",so they
still contain original data edited by users, but they aren't meant to
be accessed procedurally by the user in arbitrary situations. They are
also be hidden in the spreadsheet and the attribute list.
Until 4.0, the attributes are still written to and read from the mesh
in the old way, so neither forward nor backward compatibility are
affected. This means memory requirements will be increased by one byte
per element when selection is used. When the flags are removed
completely, requirements will decrease.
Further notes:
* The `MVert` flag is empty at runtime now, so it can be ignored.
* `BMesh` is unchanged, otherwise the change would be much larger.
* Many tests have slightly different results, since the selection
attribute uses more generic propagation. Previously you couldn't
really rely on edit mode selections being propagated procedurally.
Now it mostly works as expected.

This is very similar to D14077. There are two differences though.
First is that vertex creases are already stored in a separate layer,
and second is that we can now completely remove use of `Mesh.cd_flag`,
since that information is now inherent to whether the layers exist.
There are two functional differences here:
* Operators are used to add and remove layers instead of a property.
* The "crease" attribute can be created and removed by geometry nodes.
The second change should make various geometry nodes slightly faster,
since the "crease" attribute was always processed before. Creases are
now interpolated generically in the CustomData API too, which should
help maintain the values across edits better.
Meshes get an `edge_creases` RNA property like the existing vertex
property, to provide more efficient access to the data in Cycles.
One test failure is expected, where different rounding between float
the old char storage means that 5 additional points are scattered in
a geometry nodes test.

The mesh's triangulation cache is often created for other operations
besides the drawing code, but during the mesh draw cache extraction
it is recalculated on every single time. It is simpler and faster to use
the existing MLoopTri array. It can also save memory if the cache
already exists by avoiding allocating a duplicate array. For a 4 million
face quad mesh, that is already 128 MB.
Also use face normals for mesh triangulation if they aren't dirty,
which should provide a general speedup when they're both necessary.
Recently 54182e4925 made this more reliable, since the triangulation
cache is invalidated properly when the mesh is deformed.

Similar to the other refactors from T95965, this commit moves sculpt
face sets to use a generic integer attribute named `".sculpt_face_set"`.
This makes face sets accessible in the Python API.
The attribute is not visible in the attributes list or the spreadsheet
because it is meant for internal use, though that could be an option
in the future along with other similar attributes. Currently the change
is small, but in the future this could simplify code by allowing use
of more generic attribute APIs.

Whenever animation on nodes was transfered to/from nodegroups (grouping/
ungrouping/separating) via BKE_animdata_transfer_by_basepath, it was
possible to create new nodes with the same name (in the formerly same
path -- see report for an example of this) and animation from the
original node was still performed on them. Issue went away after save/
reload.
In order to fully update the action, a depsgraph is now performed on the
action (similar to what is done when renaming for example).

Following {T54811} (and {rBbb92edd1c802}), DEG updates have been added
to the various operators. This has also been done for the layers
operators (see {rBf998bad211ae}, `ARMATURE_OT_bone_layers` has been
marked done in T54811). However, instead of `ARMATURE_OT_bone_layers`,
the update tagging actually happened for `POSE_OT_bone_layers`.
Now do this for `ARMATURE_OT_bone_layers` as well (keep it for
`POSE_OT_bone_layers`, dont think this is wrong there either).

This is already the case for most CMake usage.
Although some find modules are an exception to this, as they were
originally maintained externally they use some different conventions.

Points cannot be selected atm in editmode, this patch just shows the
selection from sculptmode in editmode.
Since the selection in sculptmode is a float, a point is considered
selected as soon as the float selection is above 0.0f.
Implementation: this piggy-back on the existing drawing via
overlay_edit_curve_point.glsl which requires a "data" VBO which holds
flags for selection (next to others such as "active" - which we also
have to take care of later).

For the Metal shader translation support for shader-global uniforms are remapped via macro's, and in such cases where a uniform name matches a vertex attribute name, compilation errors will occur due to this injected syntax being incompatible with the immediate code.
Also adding source-level function interface alternatives where sized arrays are passed in. These are not supported directly in Metal shading language and are instead handled as pointers. These pointers require explicit address-space qualifiers in some cases, if device/constant address space memory is passed into the function.

These implementations remove dependency on the Geometry pass by instead invoking one vertex shader instance for each expected output vertex, matching what a geometry shader would emit. Each vertex shader instance is then responsible for calculating the same output position based on its vertex_id as the logic would in the geometry shader version.
SSBO Vertex fetch enables full random-access into a vertex buffer by binding it as a read-only SSBO. This enables each instance to read neighbouring vertex data to perform contextual calculations as a geometry shader would, for cases where attribute Multiload is not supported.

MTLContext provides functionality for command encoding, binding management and graphics device management. MTLImmediate provides simple draw enablement with dynamically encoded data. These draws utilise temporary scratch buffer memory to provide minimal bandwidth overhead during workload submission.
This patch also contains empty placeholders for MTLBatch and MTLDrawList to enable testing of first pixels on-screen without failure.
The Metal API also requires access to the GHOST_Context to ensure the same pre-initialized Metal GPU device is used by the viewport. Given the explicit nature of Metal, explicit control is also needed over presentation, to ensure correct work scheduling and rendering pipeline state.

From the nodes' description: "Retrieve the object that contains
the geometry nodes modifier currently being executed". This was
discussed in the most recent geometry nodes module meeting.
Because the node allows you to retrieve the position of the modifier
object, it has to add a depsgraph relation to object transform.
Expect that modifiers will be reevaluated when moving the object.
In the future, better static analysis of node trees could make this
check smarter.
