[feat request] Add `metadata_log_entries` metadata table

[kevinjqliu]

Feature Request / Improvement

Similar to the Spark metadata table https://iceberg.apache.org/docs/nightly/spark-queries/#metadata-log-entries

which uses the metadata-log field in the Table's Metadata (See https://iceberg.apache.org/spec/#table-metadata-fields)
