tools headers: Import iosubmit_cmds512()

Import iosubmit_cmds512() from arch/x86/include/asm/io.h into tools/ so
it can be used by VFIO selftests to interact with Intel DSA devices.

Also pull in movdir64b() from arch/x86/include/asm/special_insns.h into
tools/, which is the underlying instruction used by iosubmit_cmds512().

Changes made when importing: None
