[API Proposal]: Add GetDeclaredSymbol overload for LocalFunctionStatementSyntax

[CollinAlpert]

Background and Motivation

For the sake of completeness, an extension method on SemanticModel should exist for LocalFunctionStatementSyntax. Note that such an overload already exists on the CSharpSemanticModel.

Proposed API

namespace Microsoft.CodeAnalysis.CSharp
{
     public static class CSharpExtensions
     {
+        public static IMethodSymbol? GetDeclaredSymbol(this SemanticModel? semanticModel, LocalFunctionStatementSyntax node, CancellationToken cancellationToken = default(CancellationToken));
     }

Usage Examples

using Microsoft.CodeAnalysis.CSharp;

void M(SemanticModel m, LocalFunctionStatementSyntax s)
{
    IMethodSymbol symbol = m.GetDeclaredSymbol(s);
}

Should likely be typed to return an IMethodSymbol

[CollinAlpert]

That was my initial thought as well, however it seems the method in CSharpSemanticModel returns an ISymbol.

@CollinAlpert tweak here: #71034

[CollinAlpert]

Cool! I've tweaked the proposal.

[CyrusNajmabadi]

Awesome. Thanks. I'll drive this!
