EEVEE: ScreenSpaceReflections: Add back support for planar reflections

We now have a new buffer to output reflection depth. This buffer is
only usefull for non planar SSR but we use it to tag the planar rays.

This also touch the raytrace algo for planars to avoid degenerate
lines on vert sharp reflections.

Fix T86429 EEVEE: Ambient occlusion broken on some platform

This was cause by a division by 0 if the ray direction had no
depth difference. Adding a small epsilon fix the issue.

Cleanup: EEVEE: Remove unused function and fix comment

EEVEE: ScreenSpaceReflections: Improve minimal hit threshold

This makes the hit delta threshold dependant on the ray angle.
If the ray is more aligned with the view, its intersection
threshold gets bigger to avoid going through geometry.

This improves reflections and fix T86448 refraction issue.

Add 'foreach_nodeclass' for geometry nodetrees

This way we get a choice when we click on node links in the Properties
Editor.

This also changes some of the more permissive poll functions on some
nodes back to being "shading-only" (these were made permissive in
rBb78f2675d7e5 for simulation nodes, but have not found their way into
geometry nodes yet).

Fix T86416: geometry nodes crash choosing a group node link menu

Since rBb279fef85d1a, the nodes properties for geometry nodes using a
texture are displayed in the Properties Editor.

It was possible to create recursive nodetrees when choosing the 'root'
nodegroup in the node link menu though leading to a crash.

Now poll if a group node of a particular node could actually be added to
the current tree.

Also check if the tree types actually match.

Fix wrong white point of Linear ACES in config reading and the bundled config

The Blender/Cycles XYZ color space has a D65 white point instead of E, and
this was not correctly accounted for both in the OpenColor config reading code
and the bundled config.

This meant that since the OpenColorIO v2 upgrade, the Linear ACES color space
was not working correctly, and other OpenColorIO configs defining
aces_interchange were not interpreted correctly.

Geometry Nodes: Add color to boolean implicit conversion

This conversion works the same way as a combination of the existing
color to float3 to boolean conversions, so the boolean result will be
false if the color is black, otherwise true, and the alpha is ignored.

Cryptomatte tests: Fix layer_from_manifest failure.

Nodes: Sortable Multi Input Sockets

This Patch removes the auto sorting from Multi-Input Sockets and allows
the links to be sorted by drag and drop instead.
As a minor related change, it fixes the drawing of the mute line to
connect to the first input instead of the socket's center.

Cleanup: unused warning building as a Python module

Fix T67190: Edge Loop Select doesn't support non-manifold edges

- New Walker added `bmw_NonManifoldedgeWalker_type`.
- This walks over edges connected with 3 or more faces connected.

Geometry Nodes: transfer polygon attributes to points in Point Distribute node

Geometry Nodes: move geometry component type enum to C

This allows us to use it in rna for the spreadsheet editor.

DNA: add defaults for UnifiedPaintSettings

Newly created scenes had unified paint settings zeroed. see T80164

Spreadsheet: new spreadsheet editor

This implements the MVP for the new spreadsheet editor (T85879). The functionality
is still very limited, but it proved to be useful already. A more complete picture
of where we want to go with the new editor can be found in T86279.

Supported features:
* Show point attributes of evaluated meshes (no original data, no other domains,
no other geometry types, yet). Since only meshes are supported right now, the
output of the Point Distribute is not shown, because it is a point cloud.
* Only show data for selected vertices when the mesh is in edit mode.
Different parts of Blender keep track of selection state and original-indices with
varying degrees of success. Therefore, when the selected-only filter is used, the
result might be a bit confusing when using some modifiers or nodes. This will
be improved in the future.
* All data is readonly. Since only evaluated data is displayed currently, it has to
be readonly. However, this is not an inherent limitation of the spreadsheet editor.
In the future editable data will be displayed as well.

Some boilerplate code for the new editor has been committed before in
rB9cb5f0a2282a7a84f7f8636b43a32bdc04b51cd5.

It would be good to let the spreadsheet editor mature for a couple of weeks as part
of the geometry nodes project. Then other modules are invited to show their own data
in the new editor!

Geometry Nodes: handle same socket being linked to input more than once better

Note, this does not allow users to connect the same socket more than once to
a multi-input-socket in the UI. However, the situation could still happen when
using node muting.

Cleanup: spelling

Cleanup: remove annotations from startup scripts

The current convention is not to use annotations for UI/startup scripts.

Cleanup: compiler warning (ignored-qualifiers)
