Add profile events: ParquetReadRowGroups and ParquetPrunedRowGroups

Why it matters

This feature enables users to monitor how many Parquet row groups are actually read versus pruned by the index during query execution, improving insight into query performance and efficiency when working with Parquet files.

How to use it

Users can monitor these new profile events in their query profiling to analyze Parquet index pruning effectiveness. No explicit configuration is needed; these events are available as part of the query profile data.
