Support Partial deletes

[Fokko]

Feature Request / Improvement

Today we only support full deletes (overwrite). Supporting partial deletes can be achieved at several places in Iceberg:

• Pure delete operations:
  • Deleting a manifest from the manifest list
  • Deleting a manifest entry from a manifest
• Rewrite operation:
  • Rewriting existing Parquet files that contain rows that match the predicate

Pure metadata deletes can be achieved using #518 and #539. For the rewrite operations, we need an API to ensure we're pluggable for other query engines. This would entail a source path (including delete-on-read files), destination-path, and a residual filter that needs to be applied to the file.
