Summary: In this change, we implement a `BlockPrinter` which orders records in a Block that's been indexed by the `BlockIndexer`. This is used in the `llvm-xray fdr-dump` tool which ties together the various types and utilities we've been working on, to allow for inspection of XRay FDR mode traces both with and without verification. This change is the final step of the refactoring of D50441.
