Summary:
Remove the dependency on `allow_db_generated_files` option in `IngestExternalFile` to be set for ingesting external tables. The files are created by SstFileWriter, and we should be able to ingest them. We could make it work by having the external table implementation provide the version and global sequence number related properties, but its safer to have RocksDB generate the table properties block and store it as is in the file.
