Summary:
One of the parameters for constructing a Compaction object is `earliest_snapshot`, which is required for Standalone Range Deletion Optimization (introduced in [https://github.com/facebook/rocksdb/pull/13078](https://github.com/facebook/rocksdb/pull/13078)). Remote Compaction has been using the `CompactionPicker::CompactFiles()` API to create the Compaction object, but this API never sets the `earliest_snapshot` parameter. To address this, update `CompactionPicker::CompactFiles()` to optionally accept `earliest_snapshot` and pass it during the call in `DBImplSecondary::CompactWithoutInstallation()`.
