vfio: selftests: Replicate tests across all iommu_modes
Automatically replicate vfio_dma_mapping_test and vfio_pci_driver_test
across all supported IOMMU modes using fixture variants. Both of these
tests exercise DMA mapping to some degree so having automatic coverage
across all IOMMU modes will help catch bugs.

vfio: selftests: Encapsulate IOMMU mode
Encapsulate the "IOMMU mode" a test should use behind a new struct.
In the future this will be used to support other types of IOMMUs besides
VFIO_TYPE1_IOMMU, and allow users to select the mode on the command
line.
No functional change intended.

vfio: sefltests: Add vfio_pci_driver_test
Add a new selftest that tests all driver operations. This test serves
both as a demonstration of the driver framework, and also as a
correctness test for future drivers.
