Implement material level uniform buffer (WebGPU initially) about engine HOT 3 OPEN

In terms of architecture, I would very much like a Material (or derived class) be just the material properties (and state) plus the update function to mark the material as dirty. But all details relating to uniforms/rendering should ideally be owned/managed by the renderer. This would help simplify our material classes massively.

There are sometimes even global uniform, e.g. time or windDirection that would be re-used by multiple shaders.

Yep that already works fine. Whatever is not in the view / material uniform blocks is automatically added to the mesh uniform block .. so that would be the case with those global uniforms.

At some point we might enable users to add global uniforms to the view UB, but for now they'd be per mesh.
