Store view environment map rotation in LightProbesUniform and remove EnvironmentMapUniform

[beicause]

Objective

Fixes #24084 (comment)
Also fixes EnvironmentMapLight::rotation if it is attached to a view.

Solution

Store view environment map rotation in LightProbesUniform and remove EnvironmentMapUniform

Testing

The examples works:

cargo r --example pccm --features free_camera,https
cargo r --example light_probe_blending --features free_camera,https
cargo r --example rotate_environment_map --features pbr_multi_layer_material_textures

I suspect we can remove the uniform by moving rotation to LightProbe. Also, rotate_environment_map doesn't work.

I’ve verified that the quat rotation formula looks correct (although a second pair of eyes wouldn’t hurt there 😅) and that the desired examples run and look as they did previously. I’m assuming the performance impact is minimal? Happy to remove a uniform buffer though to get further under the new webgpu limits.

Also +1 to adding a migration guide for the public facing changes!

EnvironmentMapLight::rotation on a view wasn't working? Could've sworn we fixed that at some point already.

Hmm, I think rotating before negating z is incorrect:

_20260504_162240.webm

Rotating after negating z:

_20260504_162112.webm

Shouldn't the environment map appear backward (left-handed) when viewed in a mirror?

Alright, the second behavior is consistent with 0.18.
I just haven't understood why rotating needs to be changed to after negating z in this PR.

Edit: Rotation needs to be inversed. Now it should be correct.

Broken by the force push noted in #24130; you'll need to clean up the Git history per @cart's message.

i checked out your branch and i think the rotate environmental map example looks correct, at least when i imagine myself spinning around with a reflective ball
