ringabout 2af602a5c8 deprecate NewFinalize with the ref T finalizer (#24354)
pre-existing issues:

```nim
block:
  type
    FooObj = object
      data: int
    Foo = ref ref FooObj


  proc delete(self: Foo) =
    echo self.data

  var s: Foo
  new(s, delete)
```
it crashed with arc/orc in 1.6.x and 2.x.x

```nim
block:
  type
    Foo = ref int


  proc delete(self: Foo) =
    echo self[]

  var s: Foo
  new(s, delete)
```

The simple fix is to add a type restriction for the type `T` for arc/orc
versions
```nim
  proc new*[T: object](a: var ref T, finalizer: proc (x: T) {.nimcall.})
```
