9d436aa31d Fix #147782: Workbench alpha imprecision
Regression from 1c41815c4d.

The log2/exp2 round-trip can cause imprecisions, which are especially
notable with the alpha channel.
This removes the round-trip conversion for the alpha channel.

c2e5622d50 Revert "Shaders: Remove old Preetham and Hosek sky texture models"
These are causing quite a big difference in existing files, which is not
easy to address in versioning. Since the goal of removing this was to
simplify things for us and that's not the case, just revert this change.

This reverts commit ab21755aaf.

084aefd0e0 Render: Add Multiple Scattering Sky Texture
This mode is based on the same athmospheric model as the previous one, but now
also accounts for multiple scattering and reflections from the ground.
This increases the accuracy, especially at low elevations.

Also renames some options for consistency:
- The previous "Nishita" model is now "Single Scattering"
- "Dust" is now "Aerosols"
- Default altitude is now 100m.

ab21755aaf Shaders: Remove old Preetham and Hosek sky texture models
Remove old Preetham and Hosek-Wilkie sky models, which are less accurate.
The Nishita improved model has been available for long enough.

4fe75da973 EEVEE: Remove all remaining reference of EEVEE next
This changes the engine identifier back to `BLENDER_EEVEE`.

We keep the `BLENDER_EEVEE_NEXT` identifier around for
versioning reasons (have to detect when it is the active
engine of a older file).

This also rename a bunch of pannels that were using `next`
in their name.

This is a breaking change for Addons compatibility.

68111db969 Nodes: Speedup Voronoi by changing the hash function
The 2D->2D, 3D->3D, 4D->4D hash functions used in Voronoi node were
using quite an expensive hash function. Switch these to dedicated
2D/3D/4D hash functions (pcg2d, pcg3d, pcg4d) -- these are still very
good quality, but the hash function itself is 3x-4x faster.
Which makes Voronoi node calculation overall be around 2x faster. In
some cases when using OSL, the speedup is even larger.

This visibly changes output of the Voronoi noise however. The actual
noise "behaves" the same, just if someone was depending on the noise
pattern being exactly like it was before, this will change the pattern.

Images, more performance results and details wrt OSL are in the PR.

bbfc97ad6f Move tests/data and assets to the main repository
This change moves the tests data files and publish folder of assets
repository to the main blender.git repository as LFS files.

The goal of this change is to eliminate toil of modifying tests,
cherry-picking changes to LFS branches, adding tests as part of a
PR which brings new features or fixes.

More detailed explanation and conversation can be found in the
design task.
