rust: vmstate: use const_refs_to_static
The VMStateDescriptionBuilder already needs const_refs_static, so use it to remove the need for vmstate_clock! and vmstate_struct!, as well as to simplify the implementation for scalars. If the consts in the VMState trait can reference to static VMStateDescription, scalars do not need the info_enum_to_ref! indirection and structs can implement the VMState trait themselves.
