Hang debugging
In case of a GPU hang or driver crash resulting in VK_ERROR_DEVICE_LOST errors, the environment variable DXVK_DEBUG=hang can now be used to help narrow down the crash location. Resulting log files may provide useful information in bug reports. This works best on AMD and Nvidia GPUs. See PR #5790 for details.
