We need this to register the MTTCG thread in split_cpu_thread_routine():
https://lore.kernel.org/qemu-devel/20250620172751.94231-12-phi...@linaro.org/
Better to have AccelOpsClass::[un]register_thread_rcu() hooks?
I think this is more complex than it needs to be. I think we don't actually need
different implementations between mttcg and rr: we just need to make use of current_cpu.
I'll experiment with this.
