Meta: Add option to run SerenityOS on a QEMU ISA-PC machine

Browse source 
The ISA-PC machine type provides no PCI bus support, no IOAPIC support
and other modern PC features of our generation.

This is mainly a good environment for testing abstractions in the kernel
space, and can help with improving on them for the sake of porting the
OS to other chipsets and CPU architectures.
