gpu NewComputeDevice specifies maximal memory limits, building on DefaultLimits(), which may not work on limited hardware..

Describe the bug

If we end up wondering why compute is failing (randomly) to create a new device, this is probably the reason. This is what happened with the windows UTM virtual machine on arm64, and not specifying limits fixed the issue there. Here's the docs on various downlevel versions of limits, which apparently are needed on "downlevel" hardware. https://docs.rs/wgpu/latest/wgpu/struct.Limits.html

How to reproduce

Just a reminder so we don't forget..
