This trait handles the x86-specific features of an irqchip, including
getting and setting the state of the pic, ioapic, lapics, and pit.
Also includes an empty implementation of this trait for the
KvmKernelIrqChip.

TEST=cargo test -p devices

This new module contains the irqchip trait and it's implementations. The
irqchips will work with the new hypervisor crate to abstract the
interaction between crosvm and kvm.
This just defines the irqchip trait and an empty implementation of the
KvmKernelIrqChip.

TEST=added test for creating a KvmKernelIrqChip and adding a Vcpu to it
