Support pinballs with registers from Intel's Advanced Matrix Extensions (AMX) for x86 architecture.

Sapphire Rapids and newer Intel x86 processores have AMX registers which get included in the pinballs created with SDE supporting Sapphire Rapids and newer architectures. pinball2elf needs to be changed to read/use those registers. For now, the workaround is to create pinballs with "sde -skl" so only Skylake register state gets saved in pinballs (assuming the application does not otherwise use newer AMX registers).
