sysemu: Move the VMChangeStateEntry typedef to qemu/typedefs.h

In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 1800 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous commit). Several headers include sysemu/sysemu.h just to get typedef VMChangeStateEntry. Move it from sysemu/sysemu.h to qemu/typedefs.h. Spell its structure tag the same while there. Drop the now superfluous includes of sysemu/sysemu.h from headers. Touching sysemu/sysemu.h now recompiles some 1100 objects. qemu/uuid.h also drops from 1800 to 1100, and qapi/qapi-types-run-state.h from 5000 to 4400.
