Summary:
Currently, blob file checksums are incorrectly dumped as raw bytes
in the `ldb manifest_dump` output (i.e. they are not printed as hex).
The patch fixes this and also updates some test cases to reflect that
the checksum value field in `BlobFileAddition` and `SharedBlobFileMetaData`
contains the raw checksum and not a hex string.

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.
