Dean Michael Berris 02f097e122 [XRay] Add a BlockIndexer visitor for FDR Records.
Summary:
This change adds a `BlockIndexer` type which maintains pointers to
records that belong to the same process+thread pairs. The indexing
happens with order of appearance of records as they are visited.

This version of the indexer currently only supports FDR version 3 logs,
which contain `BufferExtent` records. We will add support for v2 and v1
logs in follow-up patches.

This is another part of D50441.
