Summary:
On file systems that support storage level data checksum and reconstruction, retry SST block reads for point lookups, scans, and flush and compaction if there's a checksum mismatch on the initial read. A file system can indicate its support by setting the `FSSupportedOps::kVerifyAndReconstructRead` bit in `SupportedOps`.
