Subject: [PATCH] sst_dump --command=raw to add index offset information
 (#10873)

Summary:
Add some extra information in outputs of "sst_dump --command=raw" to help debug some issues. Right now, encoded block handle is printed out. It is more useful to directly print out offset and size.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/10873

Test Plan: Manually run it against a file and check the output.
