Vulkan: VoxelGI and LightmapGI incorrectly calculating the light for the same object

[guilhermefelipecgs]

Godot version:
master (495b287)

OS/device including version:
Arch 5.6.4-arch1-1

Issue description:
GIProbe are generating different results depending on the position of the object inside giprobe's cage:

Rotating the object also affects the calc (happens in 3.2.1 as well, maybe is related to #35200):


cube was rotated and rebaked

Steps to reproduce:
I exported a cube with inverted normals from blender.
I setup 3 spot lights for each cube.
Then I bake giprobe with interior on and light intensity to 8.

Minimal reproduction project:
giprobe_test.zip

Yea that looks like the same issue. I will press reduz about it more, as I still don't understand what is broken and why my PR fixes it.

Just a note, BakedLighmap is also affected:

@guilhermefelipecgs Can you still reproduce this in the latest master branch with VoxelGI, and with the new GPU lightmapper (LightmapGI)? You can download a nightly build here.

[guilhermefelipecgs]

The bug is still there (VoxelGI), even worse when entering in orthogonal view now.

On the other hand, looks like the LightmapGI has been fixed.
