Fix pivot pie menu missing in the clip editor

Regression in a4226a050b17f4a798445b4576e2ee34fb6ee73f.

Fix T86390 Exact Boolean crash.

The code has to keep track of "zero volume" cells and I forgot
that there were cases where that needed be be invalidated.

Cleanup: EEVEE: Remove unused mipmapping on main color buffer

Cleanup: EEVEE: Replace `brightness()` by `max_v3()`

It is more straightforward to understand and is define in common file.

Nodes: Add distance float socket type

This is necessary to make float sockets display a value with the unit
system. `PROP_DISTANCE` will be used quite a lot by the mesh primitives
geometry nodes patch.

Cleanup: EEVEE: Silence warning

EEVEE: RenderPass: Fix Ambient Occlusion pass

The shader was not using the horizon texture and was trying to
trace the AO again.

Also the depth reconstruction was off because now using the maxzBuffer.

Cleanup: EEVEE: Remove the horizon search layered shader

This shader is of no use now that we the fullres hizbuffer.

EEVEE: Planar reflections: Fix ambient occlusion broken in reflections

Use the maxzbuffer to get the correct depth information.

Nodes: Move group input and output to a consistent menu location

Currently (in geometry nodes) you can delete the group input or group
output nodes with no way to get them back without copy and paste. This
adds them to the "Group" submenu of the add menu so at least there is
a way to add them back.

Additionally, these nodes are moved to the "Group" submenu for all node
editors. This makes sense since they are not like the other input or
output nodes, they really just relate to how groups are organized.

Cleanup: EEVEE: Make bsdf_sampling_lib.glsl more tidy

Cleanup: EEVEE: Remove hammersley texture and split hammersley code

Cleanup: EEVEE: Split effect_ssr.glsl

This split is to make code easier to manage and rename the files to
`effect_reflection_*` to avoid confusion.

Also this cleans up a bit of the branching mess in the trace shader.

Cleanup: EEVEE: Remove SSR shader variations

EEVEE: Fix split commit

EEVEE: ScreenSpaceReflections: Jitter starting texel

This make sure the rays are generated randomly from a fullres
texel center.

This creates more noise but increase the convergence when doing
half res tracing.

EEVEE: ScreenSpaceReflections: Increase depth threshold

This avoids going through geometry when ray have certain angle.

EEVEE: ScreenSpaceReflections: Add back multi ray-hitpoint reuse

We now reuse 9 hitpoints from the neighboorhood using a blue noise
sample distribution as mentionned in the reference presentation.

Reusing more rays does however make some area a bit more blury.

The resulting noise is quite lower compared to previous implementation
which was only reusing 4 hits.

EEVEE: Fix wrong sss component being affected by alpha

This fixes NaNs / blown up values when using alpha-hashed transparency
or alpha clip with SSS.

Fix T86476 EEVEE: SSS material with variable radius can produce NaNs

Simple divide by 0 error. The input radius was assumed to be safe
but is not when the user can scale it arbitrarly.

This also move the division out of the loop.
