Replace qemu_system_cond with VCPU stop mechanism

We can express the VCPU thread wakeup with the stop mechanism, saving
both qemu_system_ready and the qemu_system_cond. For KVM threads, we can
just enter the main loop as long as the thread is stopped. The central
TCG thread is better held back before the loop as there can be side
effects of the services called even when all CPUs are stopped.

Creating VCPUs in stopped state will also be required for proper CPU
hotplugging support.
