cpu/x86/topology: Add tile and die ID CPU topology fields

Browse source 
This commit makes the tile and die ID CPU topology parameters
information available to support the implementation of
EFI_MP_SERVICES_PROTOCOL.GetProcessorInfo() in accordance with the
Platform Initialization Specification 1.7.

TEST=Instrumentation shows that the tile_id and die_id apic_path fields
     are properly populated.
