Move debug exception handling out of cpu_exec
To prepare splitting up KVM and TCG CPU entry/exit, move the debug exception into cpus.c and invoke cpu_handle_debug_exception on return from qemu_cpu_exec. This also allows to clean up the debug request signaling: We can assign the job of informing main-loop to qemu_system_debug_request and stop the calling cpu directly in cpu_handle_debug_exception. That means a debug stop will now only be signaled via debug_requested and not additionally via vmstop_requested.
