    [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.
