Is your feature request related to a problem or challenge?

This helps diagnostic whether a Bloom filter mismatches (because of high false-positive probability caused by suboptimal tuning) or is not used at all. For example, I used it to track down #9382 (comment)

Describe the solution you'd like

"row_groups_matched_bloom_filter" and "row_groups_matched_statistics" metrics alongside "row_groups_pruned_bloom_filter" and "row_groups_pruned_statistics".

Describe alternatives you've considered
