This is blocked on Wumpf/wgpu-profiler#75

That in turn is very likely blocked on getting a 22.0.1 release of wgpu.

Opening this here now to track that it is in progress and what's blocking it as well as call out a couple of discussion points.

1. In vello_shaders, we have a feature msl which could be changed to only happen on Apple targets by using msl-out-if-target-apple instead with Naga 22. I don't know what the upstream users of this feature want.
2. We could start to enable the work from Pipeline caching, this time not jankily #524 to improve startup time when using Vulkan.
3. ???
