Purpose
Add a new system table
$file_key_rangesthat exposes per-file keyranges (min_key, max_key), file path, and first_row_id for each data
file. This enables users and DBAs to diagnose data distribution and
Global Index (PIP-41) coverage via SQL queries.
Schema (11 fields): partition, bucket, file_path, file_format,
schema_id, level, record_count, file_size_in_bytes, min_key, max_key,
first_row_id.
PIP-41: https://cwiki.apache.org/confluence/display/PAIMON/PIP-41%3A+Introduce+FilePath+Global+Index+And+Optimizations+For+Lookup+In+Append+Table
