feat: enable zstd squashfs compression and firmware (xz) compression

Bump tools to the version with `zstd` support.

Enable kernel-level squashfs zstd decompression.

Enable firmware decompression, Linux 5.15 only supports .xz format, but
it would allow us to compress the firmware blobs in the initramfs.
