Damian Barabonkov 41e12e9d6a vmm, pci, openapi: Add VFIO mmap BAR exclusion
Allow VFIO devices to list BAR indices that should not be
mmapped into the guest. This lets operators skip large BARs that
are known not to be used by their workload.

When a BAR is skipped, the log also calls out that P2P DMA
mapping is skipped because the VFIO DMA map path uses the same
mmap backing.
