This reverts commit 83f8464f.

Reason for revert: speculative revert for blink linux failure
https://ci.chromium.org/p/v8/builders/ci/V8%20Blink%20Linux/1272

Original change's description:
> [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
> no code at all (shrinking its size from 96 bytes to 64 bytes on x64),
> but is there to allow the runtime to continue to work since it expects
> a Code object.
> 
> This reduces code_space from ~152k to ~40k (-112k) and increases
> read_only_space from 33k to 108k (+75k) in the snapshot.
>
