feat(lib/granule): Add dev_granule object type

Define dev_granule structure type and add device granule
objects to manage device memory in PCI regions.
Define device granule states:
- DEV_GRANULE_STATE_NS
- DEV_GRANULE_STATE_DELEGATED
- DEV_GRANULE_STATE_MAPPED
Add locking primitives and access functions for
dev_granule objects.
Add dev_granules[RMM_MAX_DEV_GRANULES] array of
dev_granule structures.
