[TS/JS] Pojo's API adjustment

Pojo

As it currently stands using the Pojo attribute, it compiles a pojo from a class constructor.

[<Pojo>]
type MyObject(field1: string, ?field2: string) =

    member val field1 = field1 with get,set
    member val field2 = field2 with get,set

With the above, we can use it like so

MyObject(field1 = "test", field2 = "test2")

and we would expect

{ "field1": "test", "field2": "test2" }

The following pseudocode however, would not work:

[<Pojo>]
type MyObject(field1: string, ?field2: string) =

    member val field1 = field1 with get,set
    member val field2 = field2 with get,set

// ...

type MyObject with
    [<Erase>]
    member val field3: string = undefined with get,set

// ...

MyObject(field1 = "test1", field3 = "test3)

// Compiles or errors: { field1: "test1" }

Recognise all fields in the constructor expression

It seems that the Pojo attribute picks up fields from the constructor arguments, and does not handle member properties otherwise. I would propose that a class marked Pojo should, instead, compile all setters within the constructor expression into the final Pojo.

This would greatly simplify writing Pojos.
