roms: add microvm-bios (qboot) as binary and git submodule
qboot is a minimalist x86 firmware for booting Linux kernels. It does the mininum amount of work required for the task, and it's able to boot both PVH images and bzImages without relying on option roms. This characteristics make it an ideal companion for the microvm machine type.
