Finally managed to reproduce failing test locally. |

Mesa seems to be the cause of the seg fault, opened https://gitlab.freedesktop.org/mesa/mesa/-/issues/12289. Edit: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32616 should fix this. |

Depends on
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32616 to stop CI failing.
Description
Adds the function
compact_blasas specified in #1040. This needed two more functions in wgpu-hal. These are based on DX12 and the function callEmitRaytracingAccelerationStructurePostbuildInfo(). On Vulkan this call is emulated with query sets. Compaction does not need any additional featues. Depending on the GPU and BLAS contents compaction may not be possible. In that case the BLAS will be duplicated (logic done by GPU driver).This change is shown by ray_cube_compute, which now compacts the BLAS before using it. This shows the requirements of the function.
Testing
Adds two more tests, testing valid and invalid compaction operations.
