IOperation: VB - It doesn't feel appropriate for BoundDelegateCreationExpression to implement IMethodBindingExpression

[AlekseyTs]

    /// <summary>
    /// Represents a reference to a method other than as the target of an invocation.
    /// </summary>
    public interface IMethodBindingExpression : IMemberReferenceExpression
    {
        /// <summary>
        /// Referenced method.
        /// </summary>
        IMethodSymbol Method { get; }

        /// <summary>
        /// Indicates whether the reference uses virtual semantics.
        /// </summary>
        bool IsVirtual { get; }
    }

BoundDelegateCreationExpression represents a delegate creation and its type is the target delegate, "a reference to a method other than as the target of an invocation" isn't a value, it doesn't imply a delegate involvement and is not supposed to have a type. If IMethodBindingExpression is supposed to represent a delegate creation, let's rename it and adjust its description. Otherwise, we probably should add a special node to represent a delegate creation, which will have IMethodBindingExpression as its operand.

dupe of existing bug?

Dupe of #20095, this issue is being addressed by creating a new node IDelegateCreationExpression
