vfio/pci: Introduce a vfio pci hot reset interface
Legacy vfio pci and iommufd cdev have different process to hot reset vfio device, expand current code to abstract out pci_hot_reset callback for legacy vfio, this same interface will also be used by iommufd cdev vfio device. Rename vfio_pci_hot_reset to vfio_legacy_pci_hot_reset and move it into container.c. vfio_pci_[pre/post]_reset and vfio_pci_host_match are exported so they could be called in legacy and iommufd pci_hot_reset callback.
