[wasm][debugger] Object members that are protected accessors are not displayed in debugger window even though proxy is informed about them

[thaystg]

Code:

    private void IncrementCount()
    {
        JObject myObj = new JObject();
        myObj.Add("thays", new JObject());
    }

Disable JustMyCode in Debugger settings.

Try to look at myObj in locals, you will not see the property ChildrenTokens, and we are able to see it in a .net6 app.

This is the definition of it: protected override IList<JToken> ChildrenTokens => _properties;

Current behavior - no internal members:

while in the reply we are including them:

When we switch off property level sorting the item is returned fine. For a normal, user-code non-overridden protected members the problem does not exist. For a user-code overridden protected members the problem is there as well, so it's not connected with JMC.

Mininal repro:

    public class MyObject
    {
        public int publicVar => 0;
        internal int internalVar => 1;
        protected int protectedVar => 2;
        private int privateVar => 3;
    }
    
    private void IncrementCount()
    {
        var testMe = new MyObject(); // NOT OK
    }

We can't have tests for it because the Debugger Proxy response is correct and contains all 4 members.

Proxy's response is fine:

  "result": [
    {
      "get": {

The reason: while grouping the members by protection level we were populating internalProperties part of response with internal/protected members. In fact, internalProperties does not correspond with C#'s protection level internal and describes only properties in the js code that are not acessible to the programmer. When debugging a simple js class: we can see that protected member is returned along with public member - in results: . In this issue we should remove populating internalProperties and move its contents to result.
