Expand @Value to Inline regular classes

[SentryMan]

Now can inline classes with @value

fixes #210
also part of #216

now we can have a class like:

public record Inlined(@Json.Value int value, String discarded) {
  public Inlined(int value) {
    this(value, "idk");
  }
}

and a simple adapter will be generated

@Generated("avaje-jsonb-generator:1.11-RC2")
public final class InlinedJsonAdapter implements JsonAdapter<Inlined> {

  private final JsonAdapter<Integer> adapter;

  public InlinedJsonAdapter(Jsonb jsonb) {
    this.adapter = jsonb.adapter(Integer.TYPE);
  }

  @Override
  public void toJson(JsonWriter writer, Inlined value) {
    adapter.toJson(writer, value.value());
  }

  @Override
  public Inlined fromJson(JsonReader reader) {
    return new Inlined(adapter.fromJson(reader));
  }
}
