Add a quaternion rotation socket type, and using the recently added
rotation attribute type, support the type in most of the multi-type
geometry nodes, and modifier attribute inputs and outputs.
The socket is still exposed with an XYZ Euler default value.
In the future we can add modes to this rotation value similar
to object rotations.
Rotation values have no implicit conversions to other types.
Nodes to convert to and from rotation values will be added
in a follow-up commit.
For now, the new socket type is hidden behind and experimental
option, because we haven't chosen the final color for it yet.

This commit splits the `transform_snap_object.cc` file into 4 files:
- `transform_snap_object.hh`
- `transform_snap_object.cc`
- `transform_snap_object_editmesh.cc`
- `transform_snap_object_mesh.cc`
The `transform_snap_object.hh` header, in addition to sharing common
types, allows functions defined in each of these files to be shared
between them.
This makes the code easier to read and simplifies maintenance.

Adds an optional list of panels to node trees. Each socket can be
assigned a panel. UI panels will be created in the future in the
modifier for these grouped sockets.
Panels are stored as a pointer array in node trees, next to socket
declarations. Each panel has a name, but it does not have to be unique.
In future a panel might also store whether it is visible by default and
similar information.
C API and RNA API are both added. Panels and their socket
assignments are accessible to users through another list in the "Group"
tab of the node editor sidebar.
Sockets in the same panel will remain together even when adding,
removing, or moving sockets or panels, renaming, etc.
A socket can be moved up or down within a panel but each panel
remains a contiguous block. Actual tree views may be created later.

Caused by cad897de16
The crash happens because the `SnapData_EditMesh` is removed from the
map but still accessed afterwards.
However, after cad897de16, invalidating an object's unique snap date is
no longer required.
The asset library reference isn't needed anymore for importing assets
since ccc9eef1b9. So it doesn't need to be set in the add menu context,
which simplifies code a bit.
Sometimes the modifier has never been evaluated by an active depsgraph
before it is used for rendering. In this case, the baked data was never
loaded. Now also allow checking for baked data in a non-active depsgraph.
The locking that is in-place already should probably already be enough
to make this thread-safe but maybe that could be made more explicit.
Previously, there were two independent algorithms for analysing how anonymous
attributes are used in a node tree: One that just computed the `aal::RelationsInNode`
for an entire node tree and one that performed a more in depth analysis to
determine how far anonymous attributes should be propagated.
As it turns out, both operations can also be done at the same time and the result
can be cached on the node tree. This reduces the amount of code and allows for
better code reuse.
This simplification is likely only an intermediate step as things will probably have
to be refactored further to support e.g. serial loops (#108896).
With this the simulation cache pointer is copied over to the evaluated modifier.
This allows the original modifier to be removed without breaking the evaluated
modifier, which results in better decoupling. This can avoid issues when a
non-active depsgraph is evaluated in the background while the user is manipulating
the scene.
Also, it is now assumed that the simulation cache is always allocated even if
there is no simulation (similar to run-time data). This simplifies the code.

It's possible to customize how the generated graph looks like by
passing in a custom `bNodeTreeToDotOptions`. This allows making
specialized visualizations for specific algorithms.
The face normal was used in local space whereas it is needed as a global
direction (since other vectors here are in worldspace as well --
knife_input_ray_segment() returns worldspace).
Could go into 3.3 LTS.
