[mips][builtins] Disable move non-JS linkage builtins code objects into RO_SPACE

Former CL 352bbb12 https://crrev.com/c/1893192 made an optimization that move non-JS
linkage builtins code objects into RO_SPACE, but caused v8 crash on mips platform,
so temporarily disable the change on mips platform.
