include/acpi: Add macros & definitions for resources types and flags
These enums & macros will be used to report resources with acpigen_* functions (Currently those resources are reported in northbridge.asl, but follow-up CLs will remove this file and add the need acpigen code). BUG=b:148759816 BRANCH=firmware-brya-14505.B TEST='emerge-brya coreboot chromeos-bootimage' builds correctly. Tested on an Anahera device which successfully boots to ChromeOS with kernel version 5.10.109-15688-g857e654d1705.
