[System.Text.Json] The JsonSerializer should Have "Try" method variants

[frankhaugen]

Simply put: The Serializer should have build-in Try -methods, to simplify handling of bad data. This should work just like Guid.TryParse();

So something like:

bool success = JsonSerializer.TryDeserializeObject<User>(jsonString, out var user);

Searched for issues using "System.Text.Json JsonSerializer try is:open " and found nothing, so this should not be a duplicate
