enh:Add TDengine benchmark support

[tomchon]

This PR adds support for the open-source time-series database TDengine.

TDengine supports two ingestion modes: SQL mode and stmt2 mode. The tsbs_load_tdengine tool uses SQL string concatenation for data insertion, while tsbs_load_tdenginestmt2 leverages the stmt2 binding method, which is more efficient and faster for large-scale data ingestion.

TDengine supports SQL for querying, ensuring high compatibility with existing TSBS query types. All query types in the suite are supported using the TDengine format for both IoT and CPU-only (DevOps) use cases.

We believe this PR will enhance TSBS by providing better benchmarking capabilities for TDengine and may serve as a foundation for supporting other SQL-based time-series databases in the future.
