Crash when params array used with reordered attribute arguments

The break was probably introduced by dotnet/roslyn#59750. I'll take a look.

Scenario:

```cs
using System;

class Attr : Attribute
{
    public Attr(bool b, int i, params object?[] parameters) { }
}

[Attr(i: 1, b: true)]
class Program { }
```
