This feature is going to be replaced with a more thorough refactoring
of the node group interface UI, which has actual node drawing support
and a new API for integration of panels into nodes.

The goal is to get to closer to removing `NOD_static_types.h` and to define all/most
aspects of a node in the node file itself instead. Data defined in node files is not
available when rna structs are created currently, because that happens in a preprocessing
step. This patch moves part of what was defined in `rna_nodetree.cc` to `node.cc` which
makes it easier to replace when `NOD_static_types.h` is removed.

The overall goal is to get rid of `NOD_static_types.h`. This patch removes
one usage of it to generate the `node.type` rna enum. Not all of the data
was available on `bNodeType` already, so I had to add the missing data there.

Add three new nodes for operations and inputs specific to
node group operators.
- **Selection** Whether elements are selected in the viewport
- **Set Selection** Sets the edit/sculpt selection, on the point,
face, or curve domains
- **3D Cursor** Gives the location and rotation of the 3D cursor,
in the local space of the modified object.
- **Face Set** The face set value from mesh sculpt mode,
and whether the attribute exists.
- **Set Face Set** Set sculpt face set values.
In the add menu and search, the nodes are only visible in the
"Tool" context of the geometry node editor. They also give
errors when executed by a modifier.

This function is used to retrieve the index of the n'th layer of
the specified type, if it exists. Currently the way it handles
an n value that is too big is inconsistent: if there are more
layers of different types following the ones of the correct type,
and n isn't too big, it will safely detect that the corresponding
layer is of a different type and return -1. However, if the value
results in a buffer overrun, it causes an assertion or crash.
This means that safe code should currently ensure n is always
correct, making the type check in this function pointless.
Moreover, checking the range in the caller may incur more
overhead than making this code safe.
This changes the assert into a check to ensure consistent behavior.

Add support in the UI for the edit mode of curves, mesh, and point
cloud objects. It's possible to control for which mode sand object
types the asset is available with a dropdown in the node header.
To make this per-mode filtering possible, the static asset tree
cache is now unique per context mode.

Show node group inputs in the redo panel, including the
"use attribute" toggle. There are a few limitations that will
be solved separately:
- The redo panel is _always_ drawn, there is no way to show it conditionally yet
- There is no way to add the operator name to the redo panel title yet
- Attribute search is still missing for attribute inputs

Remove the "_for_read" suffix from methods to get geometry and geometry
components. That should be considered the default, so the suffix just
adds unnecessary text. This is consistent with the attribute API and
various implicit sharing data access methods.
Use "from_mesh" instead of "create_with_mesh". This is consistent with
the recently used naming for the `IndexMask` API.

No user visible changes expected, except of new experimental feature
option.

This introduces asset shelves as a new standard UI element for accessing
assets. Based on the current context (like the active mode and/or tool), they
can provide assets for specific workflows/tasks. As such they are more limited
in functionality than the asset browser, but a lot more efficient for certain
tasks.
The asset shelf is developed as part of the brush assets project (see #101895),
but is also meant to replace the current pose library UI.
Support for asset shelves can quite easily be added to different editor types,
the following commit will add support for the 3D View. If an editor type
supports asset shelves, add-ons can chose to register an asset shelf type for
an editor with just a few lines of Python.
It should be possible to entirely remove `UILayout.asset_view_template()` once
asset shelves are non-experimental.
Some changes are to be expected still, see #107881.

Implement capture point bias. This offsets the capture
points to reduce the amount bad capture locations (i.e.:
inside objects, near walls etc...).
Two new parameters are added:
- Capture Surface Bias: Ensure a minimum distance between
capture points and surrounding geometry. This is expressed as the
relative distance between two capture point. Requires re-bake
to take effect.
- Capture Escape Bias: Moves capture points enclosed inside
objects above the nearest surface. This bias defines how far a
capture point can be moved for escaping the object. This is
expressed as the relative distance between two capture point.
Requires re-bake to take effect.
This is called virtual offset in the reference material.
A quick prepass runs before the baking to offset the samples away
from any surface that could potentially make bad samples.
In order to speedup the process, we create cluster list of surfels
near each irradiance grid point. This allow access to neighboring
surfels that can contribute to the virtual offset which should
never be more than half a cell wide.

A few places already calculated vertex normals with better contextual
information to improve performance. To allow changing the storage of
vertex normals more (mostly for improved caching), change some code
from "get normals, set values, clear dirty flag" to "make vertex
normals data, give to mesh". This makes the API less awkward too,
since previously the "get for write" and "clear dirty" calls always
had to be separated.

Implement invalid sample points filling. Improves invalid regions
but introduce light leak.
Grid sample points are considered invalid if they have a ratio of
front-face ray hit under the given threshold. This is a post-processing
pass on the baked lighting that fills dark regions produced by
invalid sample location (e.g.: inside walls) with valid neighbor
samples data.
Two new parameters are added:
- Dilation Threshold: Validity threshold under which grid samples are
considered invalid. Invalid samples will gather valid lighting data
from valid neighbors inside the dilation radius.
- Dilation Radius: Radius of the dilation process. Expressed in grid
sample distance.
The validity of each point is progressively refined just like the
lighting data during the baking process.
The dilation process is implemented as a post-processing pass during
the loading of the grid data into the irradiance atlas. This allows
live tweaking the dilation parameters.

Recently a user expressed interest in exporting baked animation
with B-Bone segments. Currently the python API already exposes
segment matrices via a PoseBone method, but there is no access
to the mapping of vertices to the segments.
Although currently the math is simple and easy to re-implement,
forcing Python add-ons to do that would cause a maintenance issue
if the mapping is ever changed later (it's quite dumb, ignoring
the rest pose curve, and there definitely is room for improvement).
This patch extracts the relevant math into a BKE function, and
exposes it in the python API as a new PoseBone method.

`NLASTRIP_TYPE_TRANSITION` was being used incorrectly as a flag, having
`NLASTRIP_TYPE_TRANSITION=1` and `NLASTRIP_TYPE_SOUND=3` in the enum
`eNlaStrip_Type`, when evaluating `NLASTRIP_TYPE_SOUND &
NLASTRIP_TYPE_TRANSITION` gives a invalid truish value.
Also `strips` that can't be placed were freed, but no removed from the
`strips list`, this will cause a error if the `strip` is at begin
or end of the list.

In `Layer::remove_frame` there is a case where the frame is not removed,
but overridden by a null-frame. In this case, the frames map was not
tagged, when it should have been.
Changing the frames map would lead to a crash later in undo.
This was because the `frames_storage` was not written to file corectly.
When the `frames_storage` was tagged dirty, it recreated the
`frames_storage.num` as well as the `keys` and `values` pointers.
The `keys` and `values` pointers were written after the update, but
since the `num` is just an `int` in the embeded struct, it was written
before being updated. This lead to an out-of-sync state and later
to the crash.
The fix makes sure we write the struct *after* updating it.
This was because the `ob->runtime.geometry_set_eval` was populated
with the new `GreasePencilComponent` but
`GeometrySet::compute_boundbox_without_instances()` did not compute
the bounding box of the grease pencil geometry.
Thus the bounding box was not correctly set and the object not
correctly rendered.
Whenever `grow_array` in
`blender/source/blender/blenkernel/intern/grease_pencil.cc` was called,
it would not free the original array after relocating the data to the
newly allocated memory. This fixes the memory leak.
Adaptation of the operator `ACTION_OT_keyframe_insert` to take into account grease pencil channels.
Grease pencil keyframes can now be inserted in blank mode, or in additive mode (duplicate the current frame in the new keyframe).
Two API functions were added :
* `add_duplicate_drawings` which copies the data of a drawing to creates a duplicate, and
* `insert_duplicate_frame` which creates a duplicate frame of an existing one either by copy or instance.
The additive mode option is also added to the UI.
The Layer method `frame_key_at` previously private was set to public.

Replace `BKE_mesh_face_flip_ex()` with `bke::mesh_flip_faces()`.
This gives better performance since it avoids custom data name
lookups for every face index, and processes data in a more cache
friendly way. Also remove the `CustomData_swap` API function
as mentioned in 09b6eac5c4.
Flipping 16 million faces, I observed a 3.25x speedup, from 760 to 230 ms.

Caused by 91b27ab637, which caused the final position
arrays to be returned in more situations (in this case, when the final
result is a non-wrapper mesh). Instead, use the cage mesh, which
is more correct anyway-- it just wasn't always available before.
Each of the four algorithms is different, and not all of them will
parallelize linearly, but for large meshes these "flushing" operations
begin to become noticeable compared to other multithreaded code.
For example, flushing visibility to vertices and edges after a change
to faces became 3.75x faster, from 90 to 24 ms.
Also avoid duplicating selection interpolation logic, use the attribute
API instead.
The aim is to replace the `BKE_mesh_faces_flip` functions with
this newer C++ function using the attribute API. But that is must
be called by RNA, so move this to blenkernel to avoid a circular
dependency between the geometry module and RNA.
