When running burn on a discrete GPU I get the following warning:

[2025-03-05T08:11:19Z WARN  wgpu_core::instance] Feature MAPPABLE_PRIMARY_BUFFERS enabled on a discrete gpu. This is a massive performance footgun and likely not what you wanted

Not sure if it's critical, but it seems it gets enabled by default in cubecl and there is no way to control it. Should cubecl probably check for the GPU type?
