Pascal Precht f3af6aa4dc feat: introduce `AddBookmark` and `RemoveBookmark` APIs to messenger 
These APIs are being introduced to address #2706 and #2704, provided
that clients will move to using these APIs instead of the currently
provided equivalent APIs in the browser service.

The `bookmarks` table is being extended with a `deleted_at` field which
can later be used for garbage collection, as "removing" a bookmark is
merely soft deletion and doesn't actually remove the data from the
database.

In addition to those APIs adding and soft deleting bookmark entries,
they also automatically perform a sync operation to ensure that
bookmarks are synced in real-time (#2704).

Closes #2706, #2704

Hash ratchet encryption

encryptor.GenerateHashRatchetKey() generates a hash ratchet key and stores it in in the DB. There, 2 new tables are created: hash_ratchet_encryption and hash_ratchet_encryption_cache. Each hash ratchet key is uniquely identified by the (groupId, keyId) pair, where keyId is derived from a clock value.

protocol.BuildHashRatchetKeyExchangeMessage builds an 1-on-1 message containing the hash ratchet key, given it's ID.

protocol.BuildHashRatchetMessage builds a hash ratchet message with arbitrary payload, given groupId. It will use the latest hash ratchet key available. encryptor.encryptWithHR encrypts the payload using Hash Ratchet algorithms. Intermediate hashes are stored in hash_ratchet_encryption_cache table.

protocol.HandleMessage uses encryptor.decryptWithHR fn for decryption.
