Normalize additional identifiers

[mikedamay]

structs and property names do not appear to be normalized resulting in the following kind of representation:

public struct Fake
{
    private int PLACEHOLDER_1;
    public int PLACEHOLDER_2()
    {
        return PLACEHOLDER_1;
    }

    public int P
    {
        get => PLACEHOLDER_1;
    }

    public int P2
    {
        get => PLACEHOLDER_1;
        set
        {
            PLACEHOLDER_1 = value;
        }
    }
    Point PLACEHOLDER_4 = new Point(X = 0, Y = 0};
}

public class PLACEHOLDER_1
{
    void PLACEHOLDER_2()
    {
        int LocalInt(int PLACEHOLDER_3) => PLACEHOLDER_3;
        var PLACEHOLDER_4 = new Dictionary<int, Func<string, string>>{{LocalInt(5), PLACEHOLDER_5 => PLACEHOLDER_5}, };
    }
}

Fake, P, P2, X, Y, LocalInt should all be normalized. This will break some tests.

This will break some tests.

I've had this situation before, which is why I've added a nifty little flag you can pass to the test.ps1 script named UpdateExpected that will update all the expected values.

The steps are:

1. Update the code to also normalize the other identifiers
2. Run test.ps1 -UpdateExpected

Disclaimer: only run this when you are confident the code works, as otherwise the expected values would be changed to something that is not correct :)
