[heap] Move even more objects into RO_SPACE 

Moves all Oddballs, empty_feedback_metadata, lots of symbols and
immortal heap numbers and several other empty collection objects.

      RO_SPACE  NEW_SPACE  OLD_SPACE  CODE_SPACE  MAP_SPACE  LO_SPACE
old      31592          0     221160       33280        176         0
