Use the OnOffAuto type as 3-state.
Since the TCGState instance is zero-initialized, the
mttcg_enabled is initialzed as AUTO (ON_OFF_AUTO_AUTO).
In tcg_init_machine(), if mttcg_enabled is still AUTO,
set a default value (effectively inlining the
default_mttcg_enabled() method content).
In the tcg_get_thread() getter, consider AUTO / OFF states
as "single", otherwise ON is "multi".
