vfio: pci: Build the KVM routes

Browse Source 
We track all MSI and MSI-X capabilities changes, which allows us to also
track all MSI and MSI-X table changes.

With both pieces of information we can build kvm irq routing tables and
map the physical device MSI/X vectors to the guest ones. Once that
mapping is in place we can toggle the VFIO IRQ API accordingly and
enable disable MSI or MSI-X interrupts, from the physical device up to
the guest.
