Refactoring for _.Property / _.MethodCall() / _.IndexerAccess[idx] shorthand for accessor functions

Now that https://github.com/dotnet/fsharp/pull/13907 is merged would be good to have code-fix for this

- [Design](https://github.com/fsharp/fslang-design/blob/main/FSharp-8.0/FS-1129-shorthand-anonymous-unary-functions.md#f-rfc-fs-1129---_-shorthand-for-simple-anonymous-unary-functions)
- [Implementation]( https://github.com/dotnet/fsharp/pull/13907)

- From `fun x -> x.Foo` to `_.Foo` and maybe the other way around too ?

```fsharp
// From
let a5 : {| Foo : int -> {| X : string |} |} -> string = fun x -> x.Foo(5).X

// To
let a5 : {| Foo : int -> {| X : string |} |} -> string = _.Foo(5).X

// From
let a6 = [1] |> List.map(fun x -> x.ToString())

// To
let a6 = [1] |> List.map _.ToString()
```
