WebGPU-Memory

This is a WebGPU-Memory tracker. You add the script to your page
before you initialize WebGPU and then for a given context
you can ask how much WebGPU memory you're using.

Note: This is only a guess as various GPUs have different
internal requirements. For example a GPU might
have alignment requirements. Still, this is likely to give
a reasonable approximation.
