Levi Tamasi cb25bc1128 Update compaction statistics to include the amount of data read from blob files (#8022) ... Summary: The patch does the following: 1) Exposes the amount of data (number of bytes) read from blob files from `BlobFileReader::GetBlob` / `Version::GetBlob`. 2) Tracks the total number and size of blobs read from blob files during a compaction (due to garbage collection or compaction filter usage) in `CompactionIterationStats` and propagates this data to `InternalStats::CompactionStats` / `CompactionJobStats`. 3) Updates the formulae for write amplification calculations to include the amount of data read from blob files. 4) Extends the compaction stats dump with a new column `Rblob(GB)` and a new line containing the total number and size of blob files in the current `Version` to complement the information about the shape and size of the LSM tree that's already there. 5) Updates `CompactionJobStats` so that the number of files and amount of data written by a compaction are broken down per file type (i.e. table/blob file). Pull Request resolved: https://github.com/facebook/rocksdb/pull/8022 Test Plan: Ran `make check` and `db_bench`.
