board: beagleboneai64: Define capsule update firmware info

Define the firmware components updatable via EFI capsule update, including
defining capsule GUIDs for the various firmware components for the
BeagleBoneAI64.

Note this involved creating BeagleBoneAI64's own beagleboneai64.h board
header file instead of reusing j721e_evm's.
