You are not wrong, but the C API sets msix_enabled and msi_enabled in
pci_alloc_irq_vectors() and clears them in pci_free_irq_vectors().

So, if we'd put it on Device<Bound> it'd be a bit of a footgun because it would
potentially yield different results depending on whether it is called before or
after obtaining an IrqVectorRegistration.
