Geometry Nodes: Expose vertex normals as an attribute

This attribute exposes mesh vertex normals as a `vertex_normal`
attribute for use with nodes. Since the normal vector stored in
vertices is only a cache of data computable from the surrounding faces,
the attribute is read-only. A proper error message for attempting to
write this attribute is part of T85749. A write-only normal attribute
will likely come later, most likely called `corner_normal`.

The normals are recomputed before reading if they are marked dirty.
This involves const write-access to the mesh, protected by the mutex
stored in `Mesh_Runtime`. This is essential for correct behavior after
nodes like "Edge Split" or nodes that adjust the position attribute.

Geometry Nodes: Sort attribute search items when menu opens

Because the search didn't run when the menu first opens, the attributes
appeared in a different order than after you typed anything into the
search field. This commit instead runs the search when the menu
is first opened, but it only sorts items without filtering.

Cleanup: Remove redundant special handling after previous commit

Not needed anymore since 3a907e742507.

Outliner: Barebones to port IDs to new Outliner tree-element code design

Continuation of work in 2e221de4ceee and 249e4df110e0 .
This prepares things so we can start porting the individual ID types to
the new code design. I already added some code for library IDs, because
they need some special handling during construction, which I didn't want
to break.

The `AbstractTreeElement::isExpandValid()` check can be removed once
types were ported and can be assumed to have a proper `expand()`
implemenation.

Also makes `TreeElementGPencilLayer` `final` which I forgot in
e0442a955bad.

Fix incorrect assert in Outliner ID deletion

Mistake in aa3a4973a30f. The expanded `ELEM()` check would include
`0 && te->idcode != 0`, which always evaluates to `false`/`0`. That
wouldn't cause the asset to fail, but the `te->idcode` part would never
be checked.

Fixed the error and cleaned up the check against "0" with a check
against `TSE_SOME_ID`, see b9e54566e3b1a.

Cleanup: Add & use enum value for ID Outliner element type

Code to check if the Outliner tree-element type was the general ID one
would always check against "0" (explicity or even implicitly). For
somebody unfamiliar with the code this is very confusing. Instead the
value should be given a name, e.g. through an enum.

Adds `TSE_SOME_ID` as the "default" ID tree-element type. Other types
may still represent IDs, as I explained in a comment at the definition.

There may also still be cases where the type is checked against "0". I
noted in the comment that such cases should be cleaned up if found.

Cleanup: Rename func occurences to _fn

Use _fn as a suffix for callbacks.

Fix crash with pinned geometry node tree with no active object

The check for a null active object was after trying to retrieve the active
modifier from the object.

Cleanup: Remove using statements.

Cleanup: use MIN2/MAX2 in compositor.

Cleanup: Make WorkPackage a struct

Cleanup: Remove unused method.

Cleanup: ExecutionSystem::find_output_execution_groups.

Cleanup: Use enum class for eChunkExecutionState.

Cleanup: Use std::Vector for chunk execution status.

Cleanup: Use blender::Vector in ExecutionGroup.

Cleanup: rename private attribtue m_max_read_buffer_offset.

Cleanup: use snake case.

Cleanup: use blender::Vector.

Cleanup: use blender::Vector.
