Add Parallel Parsing and Schema Inference for JSONAsObject Format

Why it matters

This feature improves the performance and usability of importing JSON data by enabling parallel processing and automatic detection of the data schema for the JSONAsObject format. It solves the problem of slow parsing and manual schema specification when working with JSON data represented as objects, enhancing efficiency and simplifying data ingestion.

How to use it

To use this feature, specify the input format as JSONAsObject when importing data. ClickHouse will automatically infer the schema and utilize parallel parsing to speed up data processing without requiring additional configuration from the user.
