Changyu Bi 9aa3b6f9ae Support range deletion tombstones in `CreateColumnFamilyWithImport` (#11252) ... Summary: CreateColumnFamilyWithImport() did not support range tombstones for two reasons: 1. it uses point keys of a input file to determine its boundary (smallest and largest internal key), which means range tombstones outside of the point key range will be effectively dropped. 2. it does not handle files with no point keys. Also included a fix in external_sst_file_ingestion_job.cc where the blocks read in `GetIngestedFileInfo()` can be added to block cache now (issue fixed in https://github.com/facebook/rocksdb/pull/6429). This PR adds support for exporting and importing column family with range tombstones. The main change is to add smallest internal key and largest internal key to `SstFileMetaData` that will be part of the output of `ExportColumnFamily()`. Then during `CreateColumnFamilyWithImport(...,const ExportImportFilesMetaData& metadata,...)`, file boundaries can be set from `metadata` directly. This is needed since when file boundaries are extended by range tombstones, sometimes they cannot be deduced from a file's content alone.
