<issue_title>INamedType.ToDisplayString omits delegate's parameters</issue_title>
<issue_description>Version Used: 4.3.0

Steps to Reproduce:

SymbolDisplayFormat options:

var format = new SymbolDisplayFormat(
        globalNamespaceStyle: SymbolDisplayGlobalNamespaceStyle.Omitted,
        typeQualificationStyle: SymbolDisplayTypeQualificationStyle.NameAndContainingTypesAndNamespaces,
        delegateStyle: SymbolDisplayDelegateStyle.NameAndSignature,
        miscellaneousOptions: SymbolDisplayMiscellaneousOptions.UseSpecialTypes);

Code example:

namespace A
{
    public delegate bool SyntaxReceiverCreator(int a, bool b);
}

Expected Behavior:
as delegateStyle: SymbolDisplayDelegateStyle.NameAndSignature is active, I expect INamedType.ToDisplayString(format) produces output:

bool SyntaxReceiverCreator(int a, bool b)

Actual Behavior:
INamedType.ToDisplayString(format) produces output (without parameters):

bool A.SyntaxReceiverCreator()

From parameter description:

SymbolDisplayDelegateStyle.NameAndSignature - Shows the name and the signature of the delegate (e.g. "void SomeDelegate(int x)").

<agent_instructions>Copilot, can you clarify teh docs for NameAndSignature. It should mention that this flag is just to determine if the signature will be there or not (the (...) part), but not what is shown in the signature. Control of what is in the signature should be explicitly stated using the right SymbolDisplayParameterOptions flags. </agent_instructions>

Comments on the Issue (you are @copilot in this section)

@RikkiGibson The `A.` prefix is expected since we are using `SymbolDisplayTypeQualificationStyle.NameAndContainingTypesAndNamespaces`.

I agree that the documentation of SymbolDisplayDelegateStyle.NameAndSignature indicates that the parameters are expected to be displayed. Let's fix that.</comment_new>

@RikkiGibson i'm thinking this is by-design. The parameter controls if we want the signature or not. But then the format of the signature is controlled by SymbolDisplayParameterOptions. So i think what we want instead is to just doc NameAndSignature to indicate that Parameter options should be provided.</comment_new>
