Levi Tamasi	f5bc3b99d5	Split BlobFileState into an immutable and a mutable part (#6502) ... Summary: It's never too soon to refactor something. The patch splits the recently introduced (`VersionEdit` related) `BlobFileState` into two classes `BlobFileAddition` and `BlobFileGarbage`. The idea is that once blob files are closed, they are immutable, and the only thing that changes is the amount of garbage in them. In the new design, `BlobFileAddition` contains the immutable attributes (currently, the count and total size of all blobs, checksum method, and checksum value), while `BlobFileGarbage` contains the mutable GC-related information elements (count and total size of garbage blobs). This is a better fit for the GC logic and is more consistent with how SST files are handled.
