This commit removes the indirection of aarch64_field_kind by directly using aarch64_field structs for AArch64 instruction operands. It introduces macro defines to map old enum names to the new struct values, facilitating a smoother transition. This change simplifies code readability by eliminating the need to cross-reference separate tables to determine opcode bit usage, addressing a long-standing issue with architecture complexity.
