    sim: cgen: hoist rules to the top-level build
    
    The rules seem to generate the same output as existing subdir cgen
    rules with cgen ports, so hopefully this should be correct.  These
    are the last set of codegen rules that we run in subdirs, so this
    will help unblock killing off subdir builds entirely.
