Not inlining function contains `bs.raw`

Currently for beta reduction, we always inline it.

```ocaml
let forIn : _ ->  _  -> (string -> unit [@bs]) -> unit = fun _ ->
  fun%raw o foo -> {|
  for (var i in o){
    foo(o)
  }
  |}
forIn () [%obj{x = 3 }] (fun[@bs] x -> Js.log x)
``` 
We should not inline such cases
