Meta: Add option to run SerenityOS on a QEMU MicroVM machine

Browse source 
The microvm machine type is a modern tool for kernel and firmware
developers to test their software against features like FDTs, second
IOAPIC, lack of legacy devices by default, the ability of using PCIe
without using PCI x86 IO ports, etc.

We can boot into such machine but we are limited in the functionality we
support currently for this type of virtual machine.
