Add PIC device.

The PIC device that this commit provides isn't quite complete: It needs to
interact with a userspace APIC in order to properly route interrupts,
but crosvm does not yet have a userspace APIC. In the interest of not
making this CL too much larger, the userspace APIC implementation will
come in a future CL.

BUG=chromium:908689
TEST=Unit tests in file. Integration testing is blocked on rest of split-irqchip being implemented.
