Add Apache Fory JSON benchmark

[chaokunyang]

Configuration

• API: databind
• Payloads: Users and Clients, one 1000 KB object per invocation
• Libraries: Fory JSON 1.6.0, Wast 0.0.29.1, Fastjson2 2.0.57, Jackson Databind 2.17.1,
  and Gson 2.11.0
• JMH: 2 forks, 3 threads, 5 warmup iterations at 3 seconds, and 5 measurement iterations at
  3 seconds
• Seed: 20260811114233
• Metric: throughput in operations per second; higher is better
