wgpu-core docs fail to build.

docs.rs fails to build the wgpu-core docs.

I am also trying to run cargo doc on a project of mine that uses wgpu-core, and it just hangs. It's sat here for >5m seemingly chewing up a whole core worth of performance in rustdoc. To be clear, it is not taking that long to document the whole lib. It is just sitting on wgpu-core trying to document it.

There's an upstream issue in cargo doc for this. Closing this as duplicate since already covered by
