Already in hard-freeze, so we don't have to worry about breaking changes.
Significant changes:
- LLVM 15 is used instead of 11 or 13
- /dev/shm has to be manually mounted
- Debian 12 uses libdrm 2.4.114
- reworked creating of rootfs, from debootstrap to mmdebstrap
- split `create-rootfs.sh` into `lava_build.sh`, `setup-rootfs.sh`, and `strip-rootfs.sh`
- dropped winehq repository for now (Debian wine is up-to-date enough)
- we use wine now, no need to call explicitly call wine64
- bumped libasan from version 6 to 8
