Levi Tamasi e8cb32ed67 Introduce BlobFileCache and add support for blob files to Get() (#7540) ... Summary: The patch adds blob file support to the `Get` API by extending `Version` so that whenever a blob reference is read from a file, the blob is retrieved from the corresponding blob file and passed back to the caller. (This is assuming the blob reference is valid and the blob file is actually part of the given `Version`.) It also introduces a cache of `BlobFileReader`s called `BlobFileCache` that enables sharing `BlobFileReader`s between callers. `BlobFileCache` uses the same backing cache as `TableCache`, so `max_open_files` (if specified) limits the total number of open (table + blob) files. TODO: proactively open/cache blob files and pin the cache handles of the readers in the metadata objects similarly to what `VersionBuilder::LoadTableHandlers` does for table files.
