Feature: read_parquet table function

Summary

Description for this feature.

duckdb has a useful parquet table function, we can have it in databend.

It may be duplicated with Stage Table Function in #7211.

But it's much easy to implement a parquet table function because it's easy to infer schema from parquet files.

Likely, It's same as stage table what @youngsofun is working.

Yes, we have discussed this, read_parquet could be more lightweight for developers to test the performance without loading into databend. The code could be reused when we implement StageTable.
