Serialize more types with ToString

[delatrie]

Since we use Newtonsoft.JSON with the default settings to serialize test or step parameters, some values are serialized in a less-than-optimal way:

• Enums are serialized as their underlying values instead of strings (see https://github.com/orgs/allure-framework/discussions/2560)
• Types from System.Reflection (PropertyInfo, etc) blows up
• Something else?...

Those are obvious cases when ToString would be preferrable.

For types associated with network addresses, Newtonsoft.JSON does not work well:

JsonSerializerSettings SerializerSettings = new()
{
    ReferenceLoopHandling = ReferenceLoopHandling.Ignore,
    Error = (_, args) => { args.ErrorContext.Handled = true; },
    Converters = {new Newtonsoft.Json.Converters.StringEnumConverter()}
};

var pa = new System.Net.NetworkInformation.PhysicalAddress(new byte[]{1,2,3,4,5,6});
var strValue = pa.ToString();
var jsonValue = JsonConvert.SerializeObject(pa, SerializerSettings);
Console.WriteLine($"String value is {strValue}");
Console.WriteLine($"JSON value is {jsonValue}");

/*
String value is 010203040506
JSON value is {}
*/

var ipa = new System.Net.IPAddress(new byte[]{1,1,1,1});
var strValue = ipa.ToString();
var jsonValue = JsonConvert.SerializeObject(ipa, SerializerSettings);
Console.WriteLine($"String value is {strValue}");
Console.WriteLine($"JSON value is {jsonValue}");

/*
String value is 1.1.1.1
JSON value is {"AddressFamily":"InterNetwork","IsIPv6Multicast":false,"IsIPv6LinkLocal":false,"IsIPv6SiteLocal":false,"IsIPv6Teredo":false,"IsIPv6UniqueLocal":false,"IsIPv4MappedToIPv6":false,"Address":16843009}
*/

P.S. For enum you can use the StringEnumConverter converter in the serialization options

It would be nice to have a way to add custom converters, just like we do with the TypeFormatter's
