vmm: Add ACPI Generic Initiator support

Browse Source 
Support ACPI Generic Initiator Affinity to associate
PCI devices with NUMA proximity domains

Add GenericInitiatorAffinity struct

Add from_pci_bdf() to encode PCI Segment:Bus:Device.Function

Add from_acpi_device() for ACPI device handles (future use)

Generate SRAT Type 5 entries for nodes with device_id

Improve create_slit_table() to check distance symmetry when
forward distance is missing

Track device ID to BDF mappings in DeviceManager

Includes comprehensive unit tests
