### Ⅰ. Describe what this PR did
1. Implement a custom serializer (SerialArraySerializer)
- Use SerializeWriter to directly construct the JSON structure, use the
underlying writer directly to avoid additional object creation
- Write baseType, baseTypeName, and elements separately
2. Implement a custom deserializer (SerialArrayDeserializer)
- Parse the JSONObject and reconstruct the SerialArray
- Remove the `@type` type information to facilitate unit testing
- Correctly handle Integer to Long type conversions
3. Register a custom handler
- Register the custom handler with fastjson during initialization for use
4. Provide a unit test to verify the correct serialization and
deserialization of PostgreSQL array types
### Ⅱ. Does this pull request fix one issue?
<!-- If that, add "fixes #xxx" below in the next line, for example, fixes
#97. -->
fixes #7670
### Ⅲ. Why don't you add test cases (unit test/integration test)?
### Ⅳ. Describe how to verify it
mvn clean test
### Ⅴ. Special notes for reviews
Due to historical fastjson logic, the method name `deserialize` is correct
instead of `deserialize`🤣
After this PR is completed, work on fastjson2 will continue.
