rust: pci: expose the allocated interrupt type
Add irq_type() on IrqVectorRegistration and IrqVector, wrapping the new
pci_irq_type() C function. A driver whose interrupt acknowledgment
depends on the type (MSI-X vs MSI vs INTx) queries it here rather than
assuming which type the PCI core selected.
