    Original Commit Message:
    
      Reland "Reland: [builtins] Move non-JS linkage builtins code objects into RO_SPACE"
    
      This is a reland of 855591a5
    
      Fixes break in builds that verify ReadOnlyHeap by relaxing the requirement for
      Code objects to be in CODE_SPACE in PagedSpaceObjectIterator::FromCurrentPage.

      > Reland of https://chromium-review.googlesource.com/c/v8/v8/+/1795358.

      > [builtins] Move non-JS linkage builtins code objects into RO_SPACE
      >
      > Creates an allow-list of builtins that can still go in code_space
      > including all TFJ builtins and a small manual list that should be pared
      > down in the future.
      >
      > For builtins that go in RO_SPACE a Code object is created that contains an
      > immediate trap instruction. Generally these Code objects are still no
      > smaller than CODE_SPACE Code objects because of the Code object alignment
      > requirements. This will hopefully be addressed in a follow-up CL either by
      > relaxing them or removing the instruction stream completely.
      >
      > In the snapshot, this reduces code_space from ~152k to ~40k (-112k) and
      > increases by the same amount.
