qemu: Formally deprecate support for qemu < 4.2

Per [1] the Debian 10 reaches EOL in August of 2022. This allows us to
bump the minimum supported qemu version to qemu-4.2 which will also
allow us to do significant cleanups.

This commit bumps the minimum qemu verison and updates the corresponding
docs.
