feat(small): Set 'summary' level metrics for DataSourceExec with parquet source

[2010YOUY01]

Which issue does this PR close?

Part of #18116

Rationale for this change

The below configuration can be used to let EXPLAIN ANALYZE only show important high-level insights.

set datafusion.explain.analyze_level = summary;

This PR sets summary level metrics for the parquet data source:

summary level metrics for DataSourceExec with Parquet source

• File level pruning metrics
• Row-group level pruning metrics
• Bytes scanned
• metadata load time
  In

  datafusion/datafusion/datasource-parquet/src/metrics.rs

  Line 29 in 155b56e

  pub struct ParquetFileMetrics {

The remaining metrics are kept in the dev level. I'm not sure if the page level pruning metrics should also be included to the summary level, I'm open to suggestions for this, or any other metrics that should also be included.

While implementing this, I came up with a few ideas to further improve metrics tracking in the Parquet scanner. I’ve documented them in #18195
