  [flang] [acc] Adding allocation to the recipe of scalar allocatables (#154643)

Currently the privatization recipe of a scalar allocatable is as follow:

```
 acc.private.recipe @privatization_ref_box_heap_i32 : !fir.ref<!fir.box<!fir.heap<i32>>> init {
  ^bb0(%arg0: !fir.ref<!fir.box<!fir.heap<i32>>>):
    %0 = fir.alloca !fir.box<!fir.heap<i32>>
    %1:2 = hlfir.declare %0 {uniq_name = "acc.private.init"} : (!fir.ref<!fir.box<!fir.heap<i32>>>) -> (!fir.ref<!fir.box<!fir.heap<i32>>>, !fir.ref<!fir.box<!fir.heap<i32>>>)
    acc.yield %1#0 : !fir.ref<!fir.box<!fir.heap<i32>>>
  }
```

This change adds the allocation for the scalar.
