devices: vfio_pci: make vfio msix cap shareable

To emulate pending bit for MSI-X, we need to add a new interrupt
delivery path in crosvm. We will make VfioPciWorker share vfio msix
cap with VfioPciDevice, fire interrupt via msix cap when receiving
irq from host device. This makes vfio msix cap shareable.

BUG=None
TEST=./tools/presubmit

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
