Local functions used as tool functions could use name cleanup

[kzu]

Description

There's a bunch of .NET reflection-originating chars in a tool name when it's created from a local function. It would be nice to to additional cleanup to get cleaner tool name by default.

Reproduction Steps

    [Fact]
    public void DefaultToolName()
    {
        static void DoSomething() { }

        var tool = AIFunctionFactory.Create(DoSomething);

        // renders _DefaultToolName_g__DoSomething_4_0
        Assert.Equal("DefaultToolName_DoSomething", tool.Name);
    }

Expected behavior

Since there can't be two members with the same name (neither at the method as well as the local function level), the name could just be DefaultToolName_DoSomething.

Actual behavior

Returns _DefaultToolName_g__DoSomething_4_0
