[codegen/dotnet] - Dynamic provider config getters

Description

Fixes #5582

Since this is incredibly difficult to write automated tests for, I confirmed that this works as expected locally by running the following program:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using Pulumi.Automation;

namespace InlineProgram
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // define our pulumi program "inline"
            var program = PulumiFn.Create(() =>
            {
                // export the website url
                return new Dictionary<string, object?>
                {
                    ["currentRegion"] = Pulumi.Aws.Config.Region,
                };
            });

            var projectName = "dynamic_config_test_dotnet";
            var stackName = "dev";

            var stackArgs = new InlineProgramArgs(projectName, stackName, program);
            var stack = await LocalWorkspace.CreateOrSelectStackAsync(stackArgs);

            await stack.Workspace.InstallPluginAsync("aws", "v4.11.0");

            await stack.SetConfigAsync("aws:region", new ConfigValue("us-west-1"));
            var result = await stack.UpAsync();
            Console.WriteLine(result.Outputs["currentRegion"].Value as String == "us-west-1" ? "test passed" : "fail");

            await stack.SetConfigAsync("aws:region", new ConfigValue("us-east-1"));
            result = await stack.UpAsync();
            Console.WriteLine(result.Outputs["currentRegion"].Value as String == "us-east-1" ? "test passed" : "fail");

            await stack.DestroyAsync();
        }
    }
}
