This patch turns the options of the Anti-Alias node into inputs.
In the process, the [0, 1] limit of the Contrast Limit input was lifted
to allow normalized arbitrary positive limits.

Deleting all points creates an empty CurvesGeometry object, all previous
attributes are lost that way. Use resize(0, 0) instead, this preserves the attributes list.

The goal here is to avoid having to cast to and from `ID` when getting the
evaluated or original ID using the depsgraph API, which is often verbose and not
type safe. To solve this, there are now `DEG_get_original` and
`DEG_get_evaluated` methods which are templated on the type and use a new
`is_ID_v` static type check to make sure it's only used with valid types.
This allows removing quite some verbosity on all the call sites. I also removed
`DEG_get_original_object`, because that does not have to be a special case
anymore.

Currently this code uses the `Mesh` struct as a value embedded in the
undo step struct. This causes the need for various hacky workarounds and
abstraction leaks. It's simpler to just allocate it in the regular way
The Shape Key ID can also be freed with the regular ID free function,
avoiding the need to expose the internal free function.

This adds support for having viewer nodes in closures. The code attempt to
detect where the closure is evaluated and shows the data from there.
If the closure is evaluated in multiple Evaluate Closure nodes, currently it
just picks the first one it finds. Support for more user control in this case
may be added a bit later. If the Evaluate Closure node is in e.g. the repeat or
foreach zone, it will automatically use the inspection index of that zone to
determine what evaluation to look at specifically.
Overall, not too much had to change conceptually to support viewers in closures.
Just some code like converting between viewer paths and compute contexts had to
be generalized a little bit.

After creating a new shading material, the new node tree might become invisible and the user has to scroll down to see the nodes.
The idea of this PR is to create nodes with x-positions centered around zero, such that they are always visible no matter the screen size or workspace setup. Ideally, the nodes' position should depend on the region's zoom and pan. However, the node creation code currently does not depend on `SpaceNode`, so such solution would complicate the code a bit. Also, this heuristic seem to work well enough for most cases.
Note: this only affects newly created materials. The material of the default cube and the default world material still have invisible nodes sometimes. This is because they are saved in the startup file, which will be addressed in a different patch.

Since nodes are not uniquely assigned to zones (some nodes are in two
zones at the same time), it's better not to expose this detail in multiple
APIs. This avoids having to explain the behavior multiple times.
Now one just has to use `get_zone_by_node/socket` and can then use
a seperate method to get the zone stack for that zone like before.
This patch turns the options of the Tone Map node into inputs.
In the process, a few changes were made. Input ranges were adjusted to
remove artificial limits. The papers indeed mention those limits, but
they were only mentioned as typical values, not valid ranges.
- The Key option is no longer limited to 1.
- Gamma is no longer limited to a value of 3.
- Intensity is no longer limited to [-8, 8].
- Contrast is no longer limited to [0, 1].
A few renames were done to clarify options and match the reference
papers.
- Offset was renamed to Balance, since it is not really an offset, but
balances between shadows and highlights. This can be looked up in the
paper.
- Correction was renamed to Chromatic Adaptation, since it doesn't
really correct anything.
- Adaptation was renamed to Light Adaptation to distinguish from
Chromatic Adaptation and now default to global tone mapping, since
this is more useful by default.

Clearing a mesh's geometry without freeing the mesh has the requirement
that the mesh remain initialized afterwards. Freeing the mesh doesn't
have that requirement and corresponds to a destructor rather than move
construction with the default value. Avoiding conflating the two
operations simplifies some future feature additions (including #122398).
Making local an intermediate collection in a liboverride hierarchy e.g.
will likely break the link between the objects in that collection, and
their hierarchy root ID (typically the top overridden collection).
This is fixed by this commit, by:
* Adding a new util, `lib_override_root_is_valid`, that check whether a
given liboverride ID is still 'connected' to its hierarchy root.
* Using this test in `BKE_lib_override_library_main_hierarchy_root_ensure`
to strengthen the detection of invalid root hierarchy pointers.
Not sure why it was not done before... But it should be fine to
completely ignore the loopback relationships (mainly liboverride
hierarchy root pointers themselves, and owners of embedded and
shape key IDs) when handling hierarchies.
Quick tests on complex production cases here also showed no obvious
issue (or even change at all) with this tweak, so think it's safe to try
it out in main.
This makes accessing these properties more convenient. Since we only ever have
const references to `CPPType`, there isn't really a benefit to using methods to
avoid mutation.

While `ComputeContextBuilder` worked well for building simple linear compute
contexts, it was fairly limiting for all the slightly more complex cases where
an entire tree of compute contexts is built. Using `ComputeContextCache` that is
easier to do more explicitly. There were only very few cases where using
`ComputeContextBuilder` would have still helped a bit, but it's not really worth
keeping that abstraction around just for those few cases.

As Relocate code temporarily removes some linked IDs from Main, this can
make collection hierarchy data invalid, in a way that will break
`BKE_main_collections_parent_relations_rebuild`.
For now, simply move that call outside of `BLO_library_link_end` and do
it after adding back all linked IDs to main.

Relocation is the only case where old and new linked data may have
a different library. This makes remapping dependencies IDs for the
liboverrides that use these linked data somewhat more challenging and
complicated.
From basic tests with both simple data, and full production-level
Mikassa char, it seems to behave fairly well now.
So far it was only possible to relocate a whole library, now one can
also relocate a single linked ID (pulling in all of its dependencies).
This is essentially linking the new data, remapping local usages of the
old linked data to the new one, removing no more used IDs, and updating
liboverrides if needed.
Previously, internal links used the same heuristics as most other nodes. However,
this is more problematic here, because I intend to use the same internal links
for the case when no closure is connected. The behavior in this case should not
change in the future if we decide to change the heuristic for internal links for
muted nodes.
Previously, the BVH bounds were updated with a top-down approach
starting at the root. As explained in #136471, algorithms that visit
every node of the tree can become a bottleneck when sculpting high-res
meshes.
This patch refactors `flush_bounds_to_parents` by using a bottom-up
approach starting from the dirty leaf nodes. This requires calculating
and storing the parents of the nodes during the BVH build.
The change reduces the overhead measured in #136471 to near zero. The
same tests give the following results:
| Radius | Node Ratio | Speedup |
|--------------|---------|------------|
| 0.10m | 297 | 1.25x |
| 0.25m | 297 | 1.23x |
| 0.50m | 551 | 1.18x |
| 1.00m | 1930 | 1.13x |
where node ratio is the ratio between total nodes and nodes affected by
the brush. For reference, typical ratios when sculpting something like
a character are very roughly:
- tens when sculpting main forms
- low hundreds when sculpting secondary forms
- high hundreds to thousands when sculpting tertiary details

For various purposes we traverse the computation done by a node tree (e.g. for
gizmos and socket usage infeferencing). For that we generally have to keep track
of the compute context we're in at any given time. During the traversal, it's
common to enter and exist the same compute contexts multiple times. Currently,
we'd always build a new compute context when that happens. That happens even
though the old one is generally still around, because other data may reference
it. This patch implements a `ComputeContextHash` type that avoids rebuilding the
same compute contexts over and over again.
I'm considering to also replace the usage of `ComputeContextBuilder` with this
cache somehow, but will see how that works out.
The reason I'm working on this now is that I have to traverse the node tree a
bit again to find where closures might be evaluated. I wanted to be able to
cache the compute contexts for a while already.

The goal is to log information about which closures are evaluated where. This
information is not exposed in the UI yet, but will be needed to be able to debug
the evaluation and inspect socket values within closures.

Remove long-deprecated constraints that will likely never be
implemented in this form.
- Rigid Body Joint Constraint was removed in 2.80, but some references
remained in the code. Versioning code was written that tried to
remove them on load, but since constraint initialization code sets
the type to CONSTRAINT_TYPE_NULL before versioning gets a chance,
the versioning code ended up never running. This has all been
removed.
- Python/Script Constraint never worked since 2.50 and showed an error
message in the UI panel.
These constraints now load as 'null' constraint, as seems to be
(looking at the code) the way that Blender currently deals with
removed constraint types. These still show up in the outliner and
python API, but have no UI panel. Removing such constraints completely
will be left for another time, as it is beyond the scope of removing
these two specific constraint types.
