Document the new `components_digests` subcomponent (tag 12) added to the
Scylla.db metadata component, which stores CRC32 digests of all checksummed
SSTable component files. Also document the trailing CRC32 digest that
stores digest of the scylla metadata itself.
Add documentation for the quarantine/ subdirectory that holds SSTables
isolated due to validation failures or corruption. Document the scrub
operation's quarantine_mode parameter options and the drop_quarantined_sstables
API operation.
Also update the directory hierarchy example to include the quarantine directory.

Closesscylladb/scylladb#27023
Introduce `ms` -- a new sstable format version which
is a hybrid of Cassandra's `me` and `da`.
It is based on `me`, but with the index components
(Summary.db and Index.db) replaced with the index
components of `da` (Partitions.db and Rows.db).
As of this patch, the version is never chosen
anywhere for writing sstables yet. It is only introduced.
We will add it to unit tests in a later commit,
and expose it to users in yet later commit.
