e2872c0bfe Core: de-duplicate bpy.context and context logging
Merges the existing `bpy.context` logging with the new `context` logging
added in [0]. In most cases `bpy.context` & `context` log the same thing.
Where the new `context` logging produces more accurate results.

d33a6a1723 Python: add function for file iteration/remapping bpy.data.file_path_foreach()
Add a function `bpy.data.file_path_foreach()` with a callback function
`visit_path_fn`:

```py
def visit_path_fn(
    owner_id: bpy.types.ID,
    file_path: str,
    _meta: typing.Any,
) -> str | None:
    return file_path.replace('xxx', 'yyy') or None

bpy.data.file_path_foreach(
    visit_path_fn,
    *,
    subset=None,
    visit_types=None,
    flags={},
)
```

When the function returns `None`, nothing happens. When it returns a
string, the reported file path is replaced with the returned string.

`subset` and `visit_types` have the same meaning as `subset` resp.
`key_types` in `bpy.data.file_path_map()`. Since the latter parameter
doesn't affect keys in a map, but rather the visited ID types, I named
it `visit_types` instead.

`flags` wraps most of `eBPathForeachFlag` as `set[str]`, with their
prefixes removed. `BKE_BPATH_FOREACH_PATH_RESOLVE_TOKEN` becomes
`RESOLVE_TOKEN`, etc. `BKE_BPATH_FOREACH_PATH_ABSOLUTE` is excluded,
as it only affects a field in the C++ callback structure that is not
passed to Python at all. If it turns out to be useful at some point,
we can always add it.

`_meta` is for future use, and is intended to give metadata of the
path (like whether it's an input or an output path, a single file or
the first file in a sequence, supports variables, etc.). By adding
this to the API now, we avoid a breaking change when this feature is
actually implemented.

e6f1cd6a29 Anim: remove deprecated XYZ_TO_RGB flag on keyframe_insert()
The `INSERTKEY_XYZ_TO_RGB` flag on `datablock.keyframe_insert()` in
Blender's Python API was changed to do nothing in #115297 and #119625,
in favor of determining fcurve coloring exclusively from user preferences.

This PR removes that now-useless `INSERTKEY_XYZ_TO_RGB` flag entirely.

df7273930f PyAPI: Add "path_from_module" function to get full bpy path to structs and props
This is to make it easy to get the bpy paths to bpy.context.property for
example. Before this change, the easiest way was to use the clipboard
bpy.ops function. However this would make the python scripts using this
fragile as it we do not have full control of what is stored in the
system clipboard.

712c507519 Logging: Do not print Python API errors that will throw an exception
Python API functions would both report an error through CLOG and throw an
exception. However this is a problem when --debug-exit-on-error is used,
as tests and other scripts will not have the opportunity to catch the exception
before Blender exits.

Now don't print such reports through CLOG. Note that these usages of
BKE_reports_init have their print level set to error, so were already not
printing info and warning reports (which is not something we generally
want Python API calls to do, they should be silent).

4e4976804e Core: Add packed linked data-blocks
This adds support for packed linked data. This is a key part of an improved
asset workflow in Blender.

Packed IDs remain considered as linked data (i.e. they cannot be edited),
but they are stored in the current blendfile. This means that they:
* Are not lost in case the library data becomes unavailable.
* Are not changed in case the library data is updated.

These packed IDs are de-duplicated across blend-files, so e.g. if a shot
file and several of its dependencies all use the same util geometry node,
there will be a single copy of that geometry node in the shot file.

In case there are several versions of a same ID (e.g. linked at different
moments from a same library, which has been modified in-between), there
will be several packed IDs.

Name collisions are averted by storing these packed IDs into a new type of
'archive' libraries (and their namespaces). These libraries:
* Only contain packed IDs.
* Are owned and managed by their 'real' library data-block, called an
  'archive parent'.

439fe8a1a0 PyAPI: support logging for Context.temp_override
Adds comprehensive logging system for temp_override context manager to
help developers debug "context is incorrect" operator poll failures.
The logging tracks all context member access during temp_override
sessions and provides detailed summaries to identify context
availability issues.

Features:
- Command-line logging: `./blender --log-level trace --log "context" `
- Python programmatic control: `temp_override_handle.logging_set(True)`
- C-level API: CTX_temp_override_logging_set/get() functions
- Tracks individual member access
- Uses CLOG logging infrastructure

The logging helps identify which context members are accessed during
temp_override sessions and whether they return valid data, making it
easier to debug operator poll functions that fail with context errors.

7eb84ebd90 Python: Print script errors with CLOG
Currently, when a python error is encountered when rendering the UI, the
corresponding message is printed to stdout / stderr via `PyErr_Print`,
this patch modifies behavior so that a cursory message is also printed
with CLOG

This has the benefit of allowing for testing via
`--debug-exit-on-error`, which aborts Blender when an error message is
printed.

c3f49cd24e Shader Nodes: add Python API for inlined shader nodes
This makes the shader node inlining from #141936 available to external renderers
which use the Python API. Existing external renderer add-ons need to be updated
to get the inlined node tree from a material like below instead of using the
original node tree of the material directly.

The main contribution are these three methods: `Material.inline_shader_nodes()`,
`Light.inline_shader_nodes()` and `World.inline_shader_nodes()`.

In theory, there could be an inlining API for node trees more generally, but
some aspects of the inlining are specific to shader nodes currently. For example
the detection of output nodes and implicit input handling. Furthermore, having
the method on e.g. `Material` instead of on the node tree might be more future
proof for the case when we want to store input properties of the material on the
`Material` which are then passed into the shader node tree.

Example from API docs:
```python
import bpy

# The materials should be retrieved from the evaluated object to make sure that
# e.g. edits of Geometry Nodes are applied.
depsgraph = bpy.context.view_layer.depsgraph
ob = bpy.context.active_object
ob_eval = depsgraph.id_eval_get(ob)
material_eval = ob_eval.material_slots[0].material

# Compute the inlined shader nodes.
# Important: Do not loose the reference to this object while accessing the inlined
#   node tree. Otherwise there will be a crash due to a dangling pointer.
inline_shader_nodes = material_eval.inline_shader_nodes()

# Get the actual inlined `bpy.types.NodeTree`.
tree = inline_shader_nodes.node_tree

for node in tree.nodes:
    print(node.name)
```

8536fd1223 Sculpt: Compress position undo step data
Stored undo step data for position changes in sculpt mode are now
automatically compressed. Compression is run in background threads,
reducing memory consumption during sculpting sessions while adding
little performance overhead.

For testing and benchmarks, memory usage is now available through
`bpy.app.undo_memory_info()`. Undo memory usage is now tracked by the
existing automated benchmark tests. Some changes to the web benchmark
visualization present the data a bit better.

ZSTD compression is run asynchronously in a backround task pool.
Compression is only blocking if the data is requested immediately for
undo/redo.

469f54f484 BPY: Implement get_transform and set_transform for runtime-defined RNA properties.
Improve handling of runtime defined python RNA properties. Mainly:
* Add `get_transform` and `set_transform` new callbacks.
  These allow to edit the value, while still using the default
  (IDProperty-based) storage system.
* Read-only properties should now be defined using a new `options` flag,
  `READ_ONLY`.
* `get`/`set` should only be used when storing data outside of the
  default system now.
  * Having a `get` without a `set` defined forces property to be
    read-only (same behavior as before).
  * Having a `set` without a `get` is now an error.
* Just like with existing `get/set` callbacks, `get_/set_transform`
  callbacks must always generate values matching the constraints defined
  by their `bpy.props` property definition (same type, within required
  range, same dimensions/sizes for the `Vector` properties, etc.).
* To simplify handling of non-statically sized strings, the relevant
  RNA API has been modified, to use `std::string` instead of
  (allocated) char arrays.

Relevant unittests and benchmarking have been added or updated as part
of this project.

Note: From initial benchmarking, 'transform' versions of get/set are
several times faster than 'real' get/set.

Implements #141042.

494b041585 Python: Improve bpy.data.user_map() argument documentation
Update the call signature in the docstring so that it is clear that the
arguments to `bpy.data.user_map()` are all optional:

```
.. method:: user_map(*, subset=None, key_types=None, value_types=None)
```

This is important for Python stubs that are generated from the
docstrings; see https://github.com/michaelgold/buildbpy/issues/3.

This change feels a bit weird, as the function behaves differently
depending on whether the arguments are there or not. For example,
`subset=None` is not actually valid, as it should be a dictionary and
the function will raise a `TypeError`. But documenting `subset=dict()`
is also incorrect, because explicitly passing that will make the
function behave differently: it reports an empty dictionary, instead of
reporting everything. The same goes for the other parameters.

A better approach (IMO) would be to either add "empty dict/set means
'everything'" logic, or to allow `None` values for these parameters so
that the documented call can actually be made.

Note that this is the case for other calls as well, such as
`bpy.data.file_path_map()`. As such, I don't want to address this in
this commit; this is just for making the docstring reflect the optional
nature of the parameters.

No functional changes.

0240a1f32f Cleanup: CMake: Modernize bf_intern_openvdb dependencies
This follows the other CMake "modernization" commits, this time for
`bf_intern_openvdb` and the OpenVDB dependency itself.

The difference with this one is that `intern/openvdb` becomes an
"optional" dependency itself. This is because downstream consumers often
want to include this dependency rather than openvdb directly, so this
target must also be optional. Optional, in this case, means the target
always exists but may be entirely empty.

Summary
- If you are using BKE APIs to access openvdb features, then use the
  `bf::blenkernel` target
- If you are only using `intern/openvdb` APIs then use the
  `bf::intern::optional::openvdb` target (rare)
- For all other cases, use the `bf::dependencies::optional::openvdb`
  target (rare)

Commit 798f85a710 changed the way the languages menu is generated in
order to improve the items' descriptions. This revealed that items in

  'Locale code: ca_AD. Translation progress: 100%'

instead of:

  'ca_AD'

To use the language code, this commit uses the menu item's identifier
