Make the compacted hal acceleration structure inherit a label from the base BLAS. #8103

 - The function you pass to `Device::on_uncaptured_error()` must now implement `Sync` in addition to `Send`, and be wrapped in `Arc` instead of `Box`.
   In exchange for this, it is no longer possible for calling `wgpu` functions while in that callback to cause a deadlock (not that we encourage you to actually do that).

 - The limits requested for a device must now satisfy `min_subgroup_size <= max_subgroup_size`. By @andyleiserson in [#8085](https://github.com/gfx-rs/wgpu/pull/8085).
