For portability, it's common to need to know the maximum size and alignment of uniform buffers. Alignment is most often 256 on NVIDIA devices due to hardware limitations, but much lower on most other GPU vendors.

I use these limits when allocating uniform buffers in my platform layer (they're fetchable in GL, too), so it would be helpful to have them in WebGPU as well.
