This allows `wgpu` to not unconditionally depend on `std::path::Path`. It’s also, in my opinion, more user-friendly, because the feature which most users will not use (and is not currently functional) is now a defaultable struct field instead of a required parameter. The disadvantage is that `wgpu-types` now has to know about tracing.
