Fix S2368 FN: constructors

[antonioaversa]

Public constructors are publicly exposed for use, and as such, S2368 should apply to them too.

public class Constructors
{
    public class AClass
    {
        public AClass(int[][] a) { } // FN
    }
}

Primary constructors should also be supported:

public class PrimaryConstructors
{
    public class C1(int[][] a);          // FN, the ctor is publicly exposed
    public class C2(int[,] a);           // FN
    public class C3(params int[] a);     // Compliant, params of int
    public class C4(params int[][][] a); // FN, params of int[][]
    public class C5(int i);              // Compliant, not a multi-dimensional array
}
