Certain packed images, like those loaded directly into memory with
`BKE_image_packfiles_from_mem`, would cause USD to process the images as
"in memory" rather than as "packed" because the API was not removing the
IMG_GEN_TILE flag.
Additionally, be sure to use the packed filepath whenever possible
rather than the name given to the Image datablock as this ensures the
correct file names are used inside the USD file and for the resulting
file on disk after export.
This also fixes 2 render tests which now match when compared to the
native renders.

In a recent commit (1), light leaking was accidentally introduced on
some objects making use of normal maps (#139870)
This commit adds a test inspired by the file in that report to avoid
issues like this reoccuring in the future.

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.

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.

When enabled, this normalize the strength by the light area, to keep
the total output the same regardless of shape or size. This is the
existing behavior.
This is supported in Cycles, EEVEE, Hydra, USD, COLLADA.
For add-ons, an API function to compute the area is added for conversion,
in case there is no native support for normalization.
area = light.area(matrix_world=ob.matrix_world)

Switch from Standard Surface to OpenPBR as the exported MaterialX surface,
since this is the new standard more renderers are adopting and it more closely
matches the Principled BSDF implementation.
Anisotropy support is improved though still not quite the same, as formulas
are different. Nodes are generated to apply anisotropic rotation to the
tangent vector, as there is no corresponding parameter in OpenPBR.

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.
