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.

Cleanup: EEVEE: Remove unused function and fix comment

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.

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.

Cleanup: EEVEE: Use correct prefix for view space vectors

EEVEE: GGX: Use distribution of visible normal for sampling

This changes the sampling routine to use the method described in
"A Simpler and Exact Sampling Routine for the GGXDistribution of Visible Normals"
by Eric Heitz.
http://jcgt.org/published/0007/04/01/slides.pdf

This avoids generating bad rays and thus improve noise level in screen-
space reflections / refraction.

EEVEE: ScreenSpaceReflections: Improve hit quality

This changes the hitBuffer to store `ReflectionDir * HitTime, invPdf`
just as the reference presentation.

This avoids issues when the hit refinement produce a coordinate that
does not land on the correct surface.

We now store the pdf in the same texture and store it inversed so we can
remove some ALU from the resolve shader.

This also rewrite the resolve shader to not be vectorized to improve
readability and scalability.

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.

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 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.
