When displaying the Hierarchies view of the Library Overrides display
mode in a specific Heist production file, Blender would become
unresponsive for about 30 seconds and every redraw in the Outliner would
lag noticably. Issue is that the sum of hierarchy elements is multiple
thousands, and that really brings the Outliner to its knees. I've looked
into some improvents and committed a few minor ones already, but it
seems it's really the big sum of elements causing the issue. There
doesn't appear to be a single bottle-neck.
To work around this, "lazy build" children, so that children of
collapsed elements are not actually created. This brings the tree
building down to some tens of miliseconds, and redrawing becomes
rather lag-free again, even with big parts of the tree un-collapsed.
Problem: Searching still needs to build the entire tree, so it's
essentially unusable right now. Should we disallow searching
altogether?
Makes the lazy-building (where children are only built when the parent
isn't collapsed) more generic, so more display modes can use it. So far
this was hardcoded for the "Data API" display mode.
This will be used to work around a big performance issue with the
Library Overrides Hierachies view in a complex production file, see
following commit.
Because children point to, or "use" their parent, the Library Overrides
Hierarchies mode in the Outliner would show parents contained in children, not
children contained in a parent. See D15339 for pictures.
In production files this would make the rig listed under all its children, so
it would appear many times in the tree. Now it appears once and the children
are collected under it.
Refactors the tree building, so instead of using
`BKE_library_foreach_ID_link()`, it now uses the ID relations mapping in
`MainIDRelations`.

Uses a inheritance based approach for querying warning of tree elements
and the mode column support of display modes.
For the warnings, tree elements can override the
`AbstractTreeElement::getWarning()` method and return a warning string.
The UI will draw the warning column with warning icons. This makes the
warning column more generalized and easier to extend to more use-cases.
E.g. library override elements will use this after a followup commit.
To support mode toggles a display mode can now just return true in the
`AbstractTreeDisplay::supportsModeColumn()` method. This makes it
trivial to add mode columns to other display modes, and less error prone
because there's no need to hunt down a bunch of display mode checks in
different places.
Adds a dropdown for the Library Overrides display mode that lets users
choose between a "Properties" and a "Hierachies" view mode. The former
is what was previously there (a mode that displays all overridden
properties with buttons to edit the values), the latter is new. It
displays the hierarchical relationships between library overridden
data-blocks. E.g. to override the mesh of an object inside a linked
collection, the entire collection > object > mesh hierarchy needs to be
overridden (whereby the former two will be automatically overridden
using system overrides).
The Hierarchies mode will also show the override hierarchies of
data-blocks that were linked and are overridden in the source file. This
information is useful to have, especially for debugging scenes.

Instead of having the "Current File" and then the individual libraries
containing indirect library overrides in the Library Overrides display
mode, only show what's in the current file. Agreement was that this
isn't very useful in this view, we may want to add it to the Hierarchy
view though (see T95802).

Also expands the top level ID type items ("Objects", "Materials", ...)
by default. See D14410 for details.

Smart pointers should be the default choice for C++ owning pointers,
since they let you manage memory using RAII.
Also moved type factory methods into static class functions.
Basically this removes any C <-> C++ glue code. C++ types are accessed
directly via the public C++ APIs.
Contains some related changes like, moving functions that were
previously declared in a now removed header to a different file, whose
header is the more appropriate place (and the source file as well).
But generally I tried to avoid other changes.
While theorically fairly generic, current code is only enabled for
bledfile and liboverride views, and only used to display messages from
library IDs.

This issue happened because of some miscommunication during the original
patch review. Since we have the parent element in other outliner modes
(Blender File, Data API) I was on the fence here. Rolling this back now
so that when Show All View Layers is off we don't see the current View
Layer top element.
The fix is simple, but it was better to format the code around to
follow the style in this file.

This is a minimal, information-only view currently, listing by default
all the override data-blocks, with their user-edited override
properties.
System-generated overrides (like the overrides of pointers to other
override data-blocks) can be shown through a filter option.
Finally, potential info or warning messages from (auto-)resync propcess
are also shown, as an icon + tooltip next to the affected items.

No functional changes. Code is ported to C++ with additional cleanups to

See https://developer.blender.org/D9499.
It's odd to include a C++ header (".hh") in C code, we should avoid that. All
of the Outliner code should be moved to C++, I don't expect this C header to
stay for long.
See https://developer.blender.org/D9499.
"View" leads to weird names like `TreeViewViewLayer` and after all they are
specific to what we call a "display mode", so "display" is more appropriate.
Also add, update and correct comments.
